Master Cylinders
Fits AUDI A4 B9 (8W2, 8WC) 40 TDI
(2015)

The brake master cylinder is part of your car's hydraulic braking system. It converts the pressure you apply to the brake pedal into a high level of hydraulic pressure which enables you to stop the car. A give away sign of a faulty master cylinder is if your brake pedal sinks to the floor without much friction as you press down. We have a fast and free delivery service available once you have selected the part for your car - just enter your registration number to find master cylinders that fit.
