The DFC DFC355-73023 Brake Master Cylinder is designed for select 2013-2017 Audi A4, A4 Quattro, A5, A5 Quattro, S4, and S5 applications. As a critical component of the hydraulic braking system, the master cylinder converts pedal force into hydraulic pressure, helping deliver consistent brake response and dependable control during everyday driving.
Built as a direct replacement for the original equipment brake master cylinder, this DFC unit is engineered to support proper fitment and reliable operation when the existing component is worn, leaking, or no longer producing consistent hydraulic pressure. Replacing a failing master cylinder can help restore a firm, predictable brake pedal and maintain the performance of the vehicle’s braking system when installed with compatible components.
Verify vehicle application and braking-system specifications before ordering to ensure proper compatibility. The DFC355-73023 is supplied as one automotive brake master cylinder. Professional installation is recommended, followed by complete brake-system inspection, proper bleeding, and confirmation of correct pedal operation.
