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 the brakes at each wheel.

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

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

Product Details

This DFC brake master cylinder is built with a cast iron housing, a strong material that helps ensure consistent hydraulic pressure for your braking system. It's designed to replace the original master cylinder on a wide range of International trucks, including models like the AB140, AM120, and R100, helping to restore proper braking function. When your master cylinder starts to wear out, you might notice a spongy brake pedal or a longer stopping distance, and replacing it is key to getting your truck to stop safely and reliably again.

This unit is a direct replacement, meaning it's made to install without needing modifications, which can make the job much smoother. The cast iron construction is a practical choice for this component, offering durability for the demanding environment of a braking system. It's a well-built part that addresses the core function of converting pedal force into hydraulic pressure, essential for bringing your International truck to a halt.
