Product Details

DFC is known for making reliable replacement parts, and this brake master cylinder is no different. If you're working on your 1988-1992 Audi 80 or 80 Quattro, this part is designed to get your braking system back to proper working order. The master cylinder is the heart of your hydraulic braking system; it converts the force from your brake pedal into hydraulic pressure that pushes the brake pads against the rotors.

This unit is built to match the original specifications of your Audi. When your master cylinder starts to fail, you might notice a spongy brake pedal, a longer stopping distance, or even brake fluid leaks. Replacing it with a direct-fit unit like this one from DFC means you won't have to worry about modifications during installation. It's designed to bolt right up where the old one came out, making the job straightforward for a mechanic.

This master cylinder is a direct replacement for several Audi models from the late 80s and early 90s, including the Audi 100 and 90. Make sure to check the fitment details to confirm it's the right part for your specific vehicle. Always bleed your brake system thoroughly after installing a new master cylinder to ensure optimal performance and safety.
