Which brake fluid should I use?

Please use the brake fluid, which is released in the owner's manual or the manufacturer. On most vehicles you will find the type on the cover of the expansion tank. Some vehicles use mineral oils. Please do not mix them with brake fluid and only use mineral oil !

General Information:
- DOT 5 is generally used for classic cars , karts, Harley , etc.. Boiling point: > 260 degrees C ° . Wet boiling point : > 180 ° C. Immiscible with other brake fluids !
- DOT 5.1 is used in almost all other motorcycles and cars. It is a synthetic brake fluid with high wet- Boiling Point. This can be mixed with DOT 4 and 5.1 products.

In order to DOT 3 ( glycol based ) and DOT 4 to obtain ( glycol based ) compatible with brake fluid DOT 5 specifications, the brake fluid DOT 5.1 has been developed based on glycol . DOT -5 fluid ( silicone based ) may be mixed with any fluid of another type.

DOT 3 glycol ( boiling point> 205 ° C / wet boiling point > 140 ° C )
DOT 4 glycol ( boiling point > 230 ° C / wet boiling point > 155 ° C )
DOT 5 silicone (boiling point> 260 ° C / wet boiling point > 180 ° C )
DOT 5.1 glycol ( boiling point> 260 ° C / wet boiling point > 180 ° C )

In particular, glycol based brake fluids attract water and should be replaced regularly . Please note that brake fluids are toxic and can damage coatings !

I didn't get a Vehicle Type Approval (ABE)/Certification (or lost it)

No problem, you'll find it in our Download-Section!

Please note: A Vehicle Type Approval is needed in DE and GB and comes in German language.

How to adjust the fittings

All probrake fittings are adjustable and rotatable (Even the pressed fittings).

Just fix the pressed area with a pliers or something similar and turn the fitting in the direction you need. This is not as easy as it sounds and you need a bit strain and maybe some additional tools.

PLEASE NOTE: If a pressed fitting turns really easy it is huge safety risk and may not be well pressed! Please report if this happens.

Always make sure you don't damage the fitting!

What is the difference between organic- and sintered metal-brakepads

It's not easy to choose wich of the two pads are the best for your bike, so we want to tell you the primary essentials, pro and contra.

Organic brakepads

*A special material mix with a high ratio of organic substances (Abrasives, filler, binder, lubricants, enforced fibre etc.)

+ up to 800 degree C heat-proof
+ lesser heat generation and attrition of the brakediscs
+ better controllable for inexperienced rider
- needs more time to gain optimal performance
- overall lower performance than sintered metal-pads
- can vitirfy when overburned

Sintered metal-pads

*100 % made of Sintered metal

+ higher friction value
+ lesser Fading
+ better performance, even when wet
+ needs lesser time to gain the optimal performance
+ needs lesser hand force
+ exact pressure point
- inappropriate for cast-discs and caliper without ceramic coating
- higher temperature on disc and pad
- some systems need a more often bleeding

How to bleed the brake-system

Bleeding the brake system is a bit tricky and allways slightly different.
Please always read the manufacturers instructions, especially when you have a ABS-System.
There are many different tools on the market wich help bleeding the brake system.
