DFC 03-11 Audi A6 Quattro Brake Master Cylinder

This DFC brake master cylinder is built with a cast iron housing, a strong material that resists corrosion and handles the pressure from your brake pedal. It's a direct replacement for the original part on a range of Audi models, including the A6 Quattro, S4, and S6. When you press the brake pedal, the master cylinder is what converts that force into hydraulic pressure, pushing brake fluid through your lines to engage the brakes. If your brakes feel spongy, or if you've noticed a fluid leak around the master cylinder, this part is likely what you need to restore proper braking performance.

DFC makes this unit to meet the original specifications for fit and function, so you can expect it to install without major modifications. The internal seals are made to hold up under the demands of the braking system, helping to prevent leaks and maintain consistent pressure. This is a critical component for your car's safety system, and replacing it with a well-built unit like this one will help ensure your brakes work as they should.
