What is the primary function of a brake master cylinder?

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, which then travels through the brake lines to activate your brake calipers or wheel cylinders.

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.

What else might I need when replacing a master cylinder?

When replacing a master cylinder, it's a good idea to have new brake fluid on hand. You'll also need to bleed the brake system to remove air and ensure proper brake function. Inspecting brake lines and hoses for any damage during the process is also recommended.
