What does a brake master cylinder do?

The brake master cylinder is the heart of your hydraulic braking system. When you press the brake pedal, it converts that mechanical force into hydraulic pressure, which then forces brake fluid to the wheels, engaging the brakes.

How do I know if my brake master cylinder needs replacing?

Common signs include a brake pedal that feels spongy or goes to the floor, a gradual loss of braking ability, or brake fluid leaks around the master cylinder itself. You may also notice the brake warning light illuminating on your dashboard.

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 bleed the brake system after installation.
