Braking Master Cylinder for Audi, Volkswagen VW, BMW & Porsche Vehicles

The brake master cylinder is the powerhouse of your brake system. When you step on the brake pedal you are activating the master cylinder. When activated the master cylinder pushes pressurized brake fluid through the brake lines and into the brake caliper. Once the fluid reaches the brake caliper the pistons inside the caliper press the brake pad onto the brake rotor, stopping the vehicle. USP offers brake master cylinders from manufacturers such as FTE, ATE, and Genuine Volkswagen and Audi. USP strongly recommends a brake fluid flush when replacing a master cylinder.
