Specialists for high-quality steel braided lines

Probrake is a renowned company that manufactures customised steel brake lines for a wide range of motorbikes and cars. Our products are characterised by first-class quality and a precise fit.

One of the first and most effective improvements you can make to your brake system is to replace the conventional rubber brake lines with our high-quality braided steel brake lines. In contrast to rubber hoses, steel braided lines are more durable and more resistant to environmental influences. According to the manufacturer's specifications, rubber brake hoses should be replaced after four years, as they are susceptible to overstretching, weathering and UV radiation.

Our braided steel brake lines offer a number of advantages over conventional rubber brake lines. They are made of specially braided stainless steel, which offers high flexibility and increased strength at the same time. This enables a more precise transmission of brake pressure and significantly improves braking reactions. In addition, steel flex lines are resistant to heat, moisture and other environmental influences, which significantly extends their service life.

At probrake GmbH, we attach great importance to quality and safety. Our steel flex lines are manufactured to the highest standards and fulfil all applicable standards and regulations. Each line is carefully inspected and tested for accuracy of fit and performance to ensure that it meets the requirements of your vehicle in every respect.

Installing our steel braided lines is simple and straightforward. They are designed as a direct replacement for the original rubber brake lines and are easy to fit. By replacing your old brake lines with steel flex lines, they significantly improve braking performance and control of your vehicle.

Rely on the experience and expertise of probrake GmbH when it comes to high-quality steel brake lines for your vehicle. We offer you first-class products, first-class service and guarantee you optimum braking performance - since 2010.


Disadvantages of rubber brake hoses

Rubber brake hoses, which are fitted as standard, have a number of disadvantages that become apparent during operation. One of these disadvantages is the stretching of the rubber lines, which can lead to overbraking. Rubber brake hoses are also sensitive to the effects of weather and UV radiation. These influences can cause the material to crack and crack. As a result, more water molecules can penetrate the brake circuit.

The consequence of this exposure to water is a reduced boiling point of the brake fluid. This can cause the pressure point of the brake to become spongy and, in the worst case, lead to complete brake failure. This poses a significant safety risk, as reliable braking performance is essential for coping with dangerous situations.
These disadvantages of rubber brake hoses emphasise the need for a high-quality alternative such as steel braided lines. Steel braided lines offer increased stability and resistance to environmental influences. They do not expand and remain flexible for longer, which enables precise transmission of brake pressure. They also offer better durability and prevent moisture from entering the brake circuit.

In order to minimise the risk of weakening and failures in the brake system, it is advisable to replace the standard rubber brake hoses with steel flex lines. This not only increases safety, but also improves braking performance. The steel flex lines ensure a reliable and precise braking effect under various conditions.


Construction of a steel flex line

The design of a steel flex brake hose is of great importance to ensure optimum performance and durability. Not all steel flex brake lines available on the market fulfil these requirements. It is therefore important to ensure that the inner core of the steel flex brake hose is made of PTFE (Teflon) when purchasing, as this guarantees almost unlimited durability.

At probrake GmbH, we attach great importance to quality and therefore only use the best materials. Our steel flex lines have an inner core made of PTFE (Teflon), which is highly resistant to brake fluid, heat and wear. This inner core ensures a smooth flow rate of the brake fluid and minimises pressure loss. This ensures precise transmission of the brake pressure and significantly improves braking reactions.

The outer part of the steel flex line consists of a robust stainless steel braid. This braiding not only provides additional strength and flexibility, but also protects the inner core from external influences such as dirt or damage. The stainless steel braiding gives the steel flex hose a high level of resistance and durability to withstand the demands of braking.


Gall-free installation of steel braided brake lines

With our steel flex brake lines, twist-free installation is absolutely hassle-free. Our lines can be rotated so that they can be installed without twisting. The fitting connection can be rotated 360°.

We recommend the following procedure for optimum installation: Hold the press sleeve or stainless steel sleeve between the fitting and the kink protection with pliers. Then use a drill or a bolt with the same internal diameter (if it is a ring connection) to guide it through the ring connection (banjo). The connection can be twisted easily and safely thanks to the leverage effect.

Our steel flex brake lines are available as ready-to-fit kits and can also be manufactured according to samples or your individual specifications or dimensions. Thanks to our many years of experience and extensive stock, we can fulfil unusual and special requirements promptly. You have the option of configuring such a brake hose directly according to your wishes in our steel flex configurator.


All steel braided lines from probrake with ABE

For over 20,000 vehicles, we offer a general operating licence (ABE) for our steel flex brake lines, which eliminates the need for registration. Please always carry the ABE with you. Clutch lines are not supplied with an ABE as they are exempt from registration. If we do not have an ABE for your vehicle, we will provide you with an expert opinion. We also supply an expert report for vehicles from abroad. With this certificate, you can have the steel flex brake lines registered without any problems. These regulations only apply to Germany.

Installation and advantages

With sufficient knowledge, you can fit the steel flex brake lines yourself. However, if you are unsure, we recommend that you have the installation carried out by a specialist workshop. The quality and reliability of steel flex brake lines have proven themselves for over 30 years, making them a popular choice for vehicle owners. The positive properties of these lines have led to more and more customers recognising and appreciating the benefits.

The almost unlimited service life of these cables eliminates the need for regular replacement intervals, thereby reducing workshop costs. Furthermore, steel flex brake lines offer the customer additional safety, such as improved modulation and a shorter braking distance. They enable a more precise and effective braking effect, which can be of decisive importance in dangerous situations.


Advantages of a steel flex brake hose

Steel-flex brake lines offer numerous advantages that have been appreciated by motorcyclists and car drivers for over 30 years. The lines are coated 8 times with a robust stainless steel mesh, which makes them extremely resistant and virtually impossible to kink, for example in the event of a fall.

The precise pressure point and improved modulation are further advantages of braided steel brake lines. This allows riders to control braking precisely and sensitively on any surface. Even trail riders appreciate the fact that the brakes no longer let up, enabling controlled braking.

Our steel braided lines are equipped with a TEFLON inner liner and are suitable for mineral oils and all brake fluids. They offer an almost unlimited service life, which eliminates the need to replace the lines at the usual intervals. Once fitted, the steel flex lines offer a long-term solution. Our special crimping system guarantees 100% tightness. In addition, the high-strength stainless steel fittings are particularly robust and will not break even in the event of a fall.

Rely on the quality and reliability of our steel braided brake lines to ensure optimum braking behaviour and a long service life. Thanks to the unique technology and benefits of these lines, you can rest assured that your brakes will work reliably and effectively at all times.


Motorbike steel flex brake lines

Motorbike steel flex brake lines play a crucial role in braking, as they contribute significantly to riding comfort. Within the braking system, the brake hose is of particular importance as it must ensure that the braking force is transmitted with as little loss as possible.

Serial rubber lines have a number of disadvantages that become apparent during operation. They expand during use, which leads to an undefined pressure point. As a result, braking force is lost and the braking distance is increased. In addition, the original brake hoses on the motorbike are usually made of rubber, which ages over time and can expand, swell or become porous under pressure. The sudden bursting of aged rubber lines occurs frequently.

Steel flex brake lines are an effective solution to these problems. Their stainless steel braided construction makes them resistant to stretching and ageing. They retain their shape and offer precise transmission of the brake pressure. As a result, the pressure point remains clearly defined and the braking force is transmitted directly and efficiently to the brakes. The result is a shorter braking distance and improved control of the motorbike.

At probrake GmbH, we attach great importance to quality and safety. Our motorbike steel flex brake lines are made from high-quality materials and meet the highest standards. They offer reliable and long-lasting performance that meets the demands of motorbike riding. Invest in steel braided brake lines to improve the braking behaviour of your motorbike and enjoy a safe riding experience.


Installation of steel braided brake lines

The installation of the steel flex brake lines can be carried out independently in accordance with the installation instructions. If you do not want to fit the lines yourself, we recommend that you have them professionally fitted in a specialist workshop. This applies in particular to vehicles with ABS, as this requires special knowledge and experience.

The motorbike steel flex brake lines are usually routed and installed in the same way as the original brake lines. However, it is often the case that alternative routes are chosen to save costs and simplify installation. This alternative routing has no influence on the function of the brake system and is also frequently used in racing.

Regardless of the chosen installation method, it is important that the steel flex brake lines are installed correctly and connected properly. This ensures safe and reliable braking performance. If you are unsure or have any questions about installation, we recommend that you contact a specialist who has the necessary expertise.


Auto steel flex brake lines

According to the manufacturer's instructions, the standard rubber lines should be replaced at the prescribed intervals (usually every 4 years). Otherwise, there is a risk of reduced braking performance and the possibility that the insurance will not cover the resulting damage.
Rubber lines can entail various risks:

  1. Overexpansion of the rubber line: If the rubber line swells too much, the brake pistons do not close quickly enough, which can lead to a longer braking distance. When the brake pedal is released, the brake pads must release the brake discs immediately. However, if the line is overstretched, the pad remains in contact for longer, the brake can overheat and wear is accelerated.
  2. Complete overstretching of the rubber line: A completely overstretched rubber line leads to complete failure of the brake. If the hoses are swollen to varying degrees, the wheels will not brake evenly. The vehicle may pull to one side or turn when braking.
  3. Spongy pressure point: A spongy pressure point often occurs when aged rubber lines are stretched to varying degrees. Too much water in the brake fluid also contributes to the pressure not being transmitted evenly, which is important for sensitive braking behaviour.

To avoid these risks and increase safety, we recommend the use of braided steel brake lines for your car. Braided steel brake lines offer greater resistance to stretching and signs of ageing. They ensure a constant and precise pressure point, which enables smooth braking.

What is the advantage of braided steel brake lines?

Compared to conventional rubber brake lines, the inside of a steel flex brake line is made of high-quality PTFE (Teflon) and is coated with a braided steel mesh for protection. This special processing offers the following main advantages for steel flex brake lines:

1. improved braking performance

Stahlflex brake lines do not expand as much under pressure as rubber lines. This means that the hydraulic energy generated by the braking process is transferred more efficiently to the brake callipers, resulting in a better and more direct braking response.

2. longer service life & less maintenance

The steel mesh protects the inner PTFE (Teflon) from external influences such as UV radiation, heat, abrasion and other mechanical stresses, thereby extending the service life of the cables. Thanks to their greater resistance to ageing and wear, steel flex lines require less maintenance and replacement than rubber brake lines.

3. higher temperature resistance & improved pressure point

During intensive braking operations, brake lines can become hot. Braided steel lines are more resistant to temperature fluctuations and offer more stable braking performance, even under extreme conditions. The constant and direct pressure point of the brake is appreciated by many riders as it provides better feedback and therefore greater control when braking. In the motorsport world, braided steel brake lines are considered the standard.

4. optics update

For many motorbike and car owners, steel braided lines also offer a visual advantage, giving the vehicle a sporty and high-quality appearance. The steel braided lines from probrake are available in numerous colours.

5. reduced fluid absorption

Stahlflex lines are less permeable to air and moisture than conventional rubber lines. This means that the brake fluid needs to be replaced less frequently because it absorbs less water.

If you are considering switching to steel flex brake lines, however, you should also ensure that the installation is carried out correctly and that you have all the necessary approvals and certifications for road use.


Are braided steel brake lines permitted & subject to registration?

Steel-flex brake lines are permitted in many countries, but they are subject to certain regulations and requirements. We will discuss the situation in Germany here, as this often serves as a reference for many other European countries:

1. general operating licence (ABE)

In Germany and many other European countries, steel flex brake lines must have a general operating licence (ABE) or an expert opinion in order to be approved for use on public roads. This ABE or expert opinion confirms that the brake lines are safe and comply with the prescribed standards.

2. entry in the vehicle documents

Even if a steel flex brake hose has an ABE, it may be necessary to present it to the TÜV (Technischer Überwachungsverein) or a similar testing organisation and have it entered in the vehicle documents. For probrake products with ABE, this step is not necessary as long as you always have the ABE with you when driving and can show it at an inspection.


How long do steel flex brake lines last?

Steel-flex brake lines are known for their durability and resistance to various environmental and operating conditions. Their service life can be influenced by the following factors:

1. material quality

The use of high-quality materials in the manufacture of steel braided lines is not just a question of aesthetics or prestige, but plays a central role in durability and reliability. High-quality steel flex lines are usually made of stainless steel, which protects the PTFE (Teflon) line from corrosion, especially when exposed to extreme conditions such as salt water or harsh weather conditions. This resistance to external influences not only extends the service life of the pipe, but also ensures consistent performance over the years. In contrast, lines made from inferior materials can often crack, leak or even break, leading to unexpected repairs and potential safety risks. Investing in high-quality steel flex lines is therefore not just an investment in a product, but also in safety, reliability and ultimately in the user's peace of mind.

2. operating conditions

The circumstances and conditions under which steel flex lines are used have a significant influence on their durability and performance. In extreme operating conditions, such as those encountered in racing, the lines are often exposed to high temperatures, constant vibrations and changing pressure conditions. Such requirements can shorten the service life of the cables and lead to premature failure. In such environments, regular maintenance and inspection is essential. In contrast, steel flex lines used under normal road conditions are exposed to less extreme stress and tend to have a longer service life. Understanding the specific requirements and operating conditions is therefore crucial for selecting the right line and planning maintenance intervals to ensure optimum performance and safety.

3. care and maintenance

The condition of steel braided lines depends not only on the quality of the material and the operating conditions, but also on the care with which they are maintained and serviced. Regular inspections are essential to ensure that there are no leaks, cracks or other signs of wear and tear. It is also important to identify and avoid potential chafing or areas where the cable could rub against other parts of the vehicle. Such rubbing can cause damage over time that will affect the integrity of the cable. It is also advisable to clean the pipes regularly to remove dirt, oil or other deposits that can lead to corrosion over time. Proper care and maintenance not only maximises the service life of the lines, but also contributes significantly to the safety of the motorbike.

4. external influences

Steel flex cables, although robust and resistant, are not completely immune to the various external influences to which they are exposed in the course of their use. Chemical influences, whether from the occasional spillage of operating fluids or contact with road salt during the winter months, can attack the outer layer of the pipes. Road salt is particularly harmful as it can accelerate corrosion, which affects the structure and integrity of the pipes. Aggressive cleaning agents that are not suitable for use on steel flex lines can have similar negative effects. It is therefore important to be aware and take precautions to counteract such harmful effects. This includes regularly rinsing the pipes, especially after travelling on gritted roads, and using mild cleaning agents that are suitable for the material. Conscious handling of external influences makes a significant contribution to maintaining the longevity and efficiency of the cables.

Stahlflex brake lines are considered particularly robust and durable in the automotive and motorbike industry. With careful maintenance and under normal operating conditions, they have the potential to reliably accompany the user for many years, often even decades. This exceptional durability is reflected in practice: probrake offers a 10-year guarantee on its steel flex brake lines.

Despite their robust construction and the associated longevity, regular inspections and maintenance should not be neglected. Any component, regardless of its quality, may show signs of wear or damage. In the case of brake lines, an unrecognised defect can harbour critical safety risks. A sudden failure of the brake line while driving can have catastrophic consequences. Safety should therefore always be the top priority. To ensure that the brake system is always in optimum condition, the brake lines should always be thoroughly checked during regular routine inspections or maintenance of the vehicle. A watchful eye and preventive measures can help to minimise potential risks and ensure the best possible performance and safety.


Is it permitted to repair brake lines?

In many countries, including Germany, the patching of brake lines is not permitted. The main reason for this is safety. A vehicle's braking system is critical to safety and any compromise to its integrity can lead to catastrophic results. If a brake line is damaged, here are the general recommendations and regulations:

1. replacement of the damaged line

A braking system is one of the most important safety features of any vehicle. Therefore, compromising on the integrity of its components is unacceptable. If a brake pipe is damaged - whether through physical damage, corrosion or other forms of wear - there is a risk that it can no longer fulfil its primary function of building up the pressure required to effectively stop the vehicle.

While it may be tempting to look for a quick fix, especially if the damage seems minor, replacing the entire line is always the safest option. Repairs often fail to fully address the underlying issues and increase the risk of re-failure in the future.

A new, undamaged replacement part ensures that the brake hose can fulfil its role in the braking system efficiently and safely. Replacing the line not only restores the integrity of the braking system, but also gives the driver an additional measure of safety and reliability on the roa
