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

The master cylinder is the heart of your vehicle's hydraulic braking system. When you press the brake pedal, it pushes fluid through the brake lines to engage the calipers or wheel cylinders, slowing your vehicle down.

What are the signs that my brake master cylinder needs to be replaced?

Common signs include a spongy or soft brake pedal, the brake warning light illuminating on your dashboard, or visible fluid leaks around the master cylinder itself. If you notice any of these issues, it's time for a replacement.

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 and amount of brake fluid separately and bleed the system after installation.

Product Details

When you're working on the braking system of your 1977 or 1978 Jeep CJ7, a reliable master cylinder is key. This component is what converts the force from your brake pedal into hydraulic pressure, pushing brake fluid through the lines to activate your brakes. If your old master cylinder is leaking or not building pressure, replacing it with a new one like this DFC unit will restore your Jeep's stopping power.

This DFC master cylinder is built to match the original specifications for your CJ7. It's designed to fit right into place, making the installation process as straightforward as possible. A properly functioning master cylinder is crucial for consistent and safe braking performance, especially when you're out on the trail or navigating everyday roads.

When installing a new master cylinder, it's a good idea to bleed your brake system thoroughly afterward to ensure all air is removed and you have a firm pedal. This part is a direct replacement, meaning it's intended to bolt up without modifications.
