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 travels through the brake lines to activate your brakes.

What are the symptoms of a failing brake master cylinder?

Common signs include a brake pedal that feels soft or spongy, a pedal that sinks to the floor when held, and a brake warning light on your dashboard. You might also notice 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 for your vehicle and fill and bleed the system after installation.

Product Details

DFC is known for making reliable replacement parts, and this brake master cylinder for your 2004-2006 Scion xB is no different. This part is crucial for your braking system; it's what converts the force from your brake pedal into hydraulic pressure that pushes the brake pads against the rotors. If your original master cylinder is leaking or not building enough pressure, your brakes will feel soft or may not work effectively.

This master cylinder is built to match the original specifications for your Scion xB, ensuring it fits right and functions as intended. It's a well-built unit designed to restore your braking system's performance. Replacing a master cylinder is a common job when you're addressing spongy brakes or a brake warning light. Once installed, you'll want to bleed your brake system to remove any air and ensure proper brake fluid circulation.
