What does a brake master cylinder do?

The master cylinder is the heart of your hydraulic braking system. When you press the brake pedal, it uses internal pistons to push brake fluid through the lines, which then activates your brakes at the wheels.

What are the symptoms of a failing master cylinder?

Common signs include a brake pedal that feels spongy or sinks to the floor when pressed, a warning light on the dashboard, or a noticeable decrease in braking performance.

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 brake fluid for your vehicle and bleed the brake system after installation.
