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

The brake master cylinder is the heart of your car's hydraulic braking system. When you press the brake pedal, it forces brake fluid through the lines to the wheels, which then applies the brakes.

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

Common signs include a brake pedal that feels spongy or sinks to the floor, a warning light on your dashboard, or a noticeable decrease in braking performance. You might also see 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 of brake fluid separately and bleed the brake system after installation.
