What are the symptoms of a failing brake master cylinder?

Common signs include a spongy or soft brake pedal that goes closer to the floor, a gradual decrease in braking ability over time, or visible brake fluid leaks around the master cylinder itself. You might also notice the brake warning light illuminating on your dashboard.

Does this DFC brake master cylinder come with brake fluid?

This part is the master cylinder unit only and does not include brake fluid. You will need to purchase the appropriate type of brake fluid for your Audi and add it after installation.

What is required after installing a new brake master cylinder?

After installing a new master cylinder, it is essential to properly bleed the brake system to remove any air that may have entered. This process ensures that hydraulic pressure is transmitted effectively to the brakes.
