What does a brake master cylinder do?

The master cylinder is the heart of your vehicle's hydraulic braking system. When you press the brake pedal, it converts that mechanical force into hydraulic pressure, pushing brake fluid through the lines to activate your 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 noticeable drop in brake fluid level without any visible leaks elsewhere, or a warning light on your dashboard related to the brake system.

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.

INFINITI QX4 2002-2003

Product Details

This DFC brake master cylinder is built with a cast iron housing, a material known for its strength and durability, making it a solid choice for your 2002 or 2003 Infiniti QX4. It's the component that takes the pressure you apply to the brake pedal and multiplies it, sending hydraulic fluid through your brake lines to engage the calipers or wheel cylinders. When this part starts to wear out, you might notice a spongy brake pedal, longer stopping distances, or even a fluid leak around the unit itself.

DFC has designed this master cylinder as a direct replacement, meaning it should fit right into your existing brake system without needing modifications. The cast iron construction helps ensure it can handle the consistent pressure cycles of braking, maintaining proper hydraulic function. This is crucial for keeping your QX4's braking system working as it should, providing the stopping power you rely on every day.

When replacing your master cylinder, it's a good idea to inspect your brake fluid level and condition, and consider bleeding the brake system afterward to ensure optimal performance and remove any air that might have entered the lines.
