What is a brake master cylinder and what does it do?

The brake master cylinder is a key component in your car's hydraulic braking system. When you press the brake pedal, it converts that mechanical force into hydraulic pressure, which then pushes brake fluid to the wheels to activate the brakes.

What are the symptoms of a failing brake master cylinder?

Common signs include a brake pedal that feels soft or spongy, a pedal that sinks to the floor when held down, or a noticeable decrease in braking performance. You might also notice brake fluid leaks around the master cylinder itself.

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 and amount of brake fluid separately and bleed the brake system thoroughly after installation.

Product Details

When you're working on the braking system of a BMW 7 Series, a failing master cylinder means you're not going to have the stopping power you need. This DFC brake master cylinder is built to replace the original unit on a wide range of BMW 7 Series models from the early 2000s through 2008, as well as the 2008-2009 Rolls-Royce Phantom. It's the component that translates the force from your brake pedal into hydraulic pressure, pushing brake fluid to your calipers and making your car stop.

This master cylinder is a well-built replacement part designed to fit right into your existing brake lines and pedal assembly. It's constructed to meet the original specifications, ensuring that the hydraulic pressure is generated correctly for consistent and reliable braking. Replacing a master cylinder is a job that requires careful attention to bleeding the brake system afterward to remove any air, but this part is designed for a straightforward installation in place of the original component.
