What does a brake master cylinder do?

The brake master cylinder converts the mechanical force from your brake pedal into hydraulic pressure. This pressure is then sent through the brake lines to actuate the brakes at each wheel, allowing your vehicle to slow down or stop.

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

Common signs include a spongy or soft brake pedal, a brake pedal that sinks to the floor when held, a visible fluid leak from the master cylinder itself, or a warning light on your dashboard indicating low brake fluid or a system issue.

Does this master cylinder come with brake fluid?

This DFC brake master cylinder does not include brake fluid. You will need to purchase the appropriate type of brake fluid for your vehicle separately and ensure the system is properly bled after installation.

Product Details

When you're working on the braking system of your 1990-1994 Audi V8 Quattro, a properly functioning brake master cylinder is essential. This component is the heart of your hydraulic braking system, converting the force from your brake pedal into hydraulic pressure that pushes the brake fluid to the calipers or wheel cylinders. If your old master cylinder is leaking, or if the pedal feels spongy and inconsistent, replacing it with a new one like this DFC unit will restore proper braking performance.

DFC builds this master cylinder to match the original specifications for your Audi V8 Quattro, ensuring it fits right and operates as expected. It's constructed with durable materials designed to handle the pressures of the braking system over time. This direct replacement means you won't have to worry about modifications during installation, making the job more straightforward. Restoring your car's braking system with a well-built master cylinder is a critical step for safety and confidence on the road.

This master cylinder is also a fit for the Audi S4 and S6 models from the specified years. Always refer to the manufacturer's installation instructions for proper bleeding procedures after installation to ensure optimal brake performance.
