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 force into hydraulic pressure, pushing brake fluid through the lines to the calipers or wheel cylinders, which then apply the brakes.

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

Common signs include a brake pedal that feels spongy or goes all the way to the floor, a gradual loss of brake fluid without any visible leaks at the lines or calipers, or a warning light on your dashboard indicating a brake system issue.

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 Acura RL separately and bleed the brake system after installation to remove air.
