What does a brake master cylinder do?

The brake master cylinder is the main component in your car's hydraulic braking system. When you press the brake pedal, it converts that force into hydraulic pressure, pushing brake fluid through the lines to activate your brakes.

What are the signs that my brake master cylinder needs replacement?

Common signs include a brake pedal that feels spongy or goes too low when pressed, a gradual loss of braking power, or brake fluid leaks around the master cylinder itself. If you notice any of these, it's important to have it inspected.

Does this master cylinder come with brake fluid?

This DFC brake master cylinder does not include brake fluid. You will need to purchase compatible brake fluid separately and bleed the brake system after installation to ensure proper operation.

Product Details

When you're working on your 1996-1998 Audi A6 Quattro, getting the right brake components is key to ensuring safe and reliable stopping. This DFC brake master cylinder is built to replace the original unit, helping to restore proper hydraulic pressure to your braking system. It's designed to be a direct fit, meaning it should install without needing modifications to your existing brake lines or mounting points.

A master cylinder is crucial because it's the heart of your car's hydraulic braking system. When you press the brake pedal, it pushes fluid through the brake lines to the calipers or wheel cylinders, which then apply pressure to the rotors or drums. If your master cylinder is leaking or failing, you might notice a spongy brake pedal, a lower pedal position, or even a complete loss of braking ability. This DFC unit aims to bring that functionality back to spec, ensuring consistent performance.

This master cylinder is specifically made for the 1996 through 1998 Audi A6 Quattro models, and also fits the 1996-1997 Audi A6. Make sure to check your vehicle's specific fitment details before installation. As with any brake job, it's a good idea to have fresh brake fluid on hand and to bleed the system thoroughly after installation to remove any air and ensure optimal performance.
