What is the main function of a brake master cylinder?

The master cylinder is the heart of your vehicle's hydraulic braking system. It takes the force you apply to the brake pedal and multiplies it into hydraulic pressure, which then travels through the brake 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 to the floor, a noticeable decrease in stopping power, or visible brake fluid leaks around the master cylinder itself. You might also hear grinding noises if the fluid level is critically low.

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 ensure the system is properly bled after installation.

Product Details

This DFC brake master cylinder is built with a cast iron housing, a material known for its strength and durability under pressure. It's designed to replace the original master cylinder on a wide range of Dodge and Plymouth vehicles from the late 70s through the early 90s, including popular models like the Dodge D150, Ramcharger, and Plymouth Trailduster. A properly functioning master cylinder is crucial for your braking system, as it converts the force from your brake pedal into hydraulic pressure that pushes the brake pads against the rotors.

When your old master cylinder starts to wear out, you might notice a spongy brake pedal, a longer stopping distance, or even brake fluid leaks. Replacing it with a new unit like this one from DFC helps restore your braking performance to its intended level. This part is a direct replacement, meaning it's made to install in the same location and connect to the same brake lines as the original equipment, simplifying the repair process.

This master cylinder is designed for vehicles that use a standard brake system. If your vehicle is equipped with ABS, you'll need to confirm compatibility with the specific ABS system. Always refer to the manufacturer's installation instructions for proper bleeding procedures after installation to ensure optimal brake performance.
