What does a brake master cylinder do?

The master cylinder converts the force from your brake pedal into hydraulic pressure. This pressure then travels through the brake lines to actuate the brakes at each wheel.

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

Common signs include a spongy or soft brake pedal, a brake pedal that sinks to the floor, reduced braking performance, or visible brake fluid leaks around the master cylinder.

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 what you get when you need to replace the original unit on your 1984 or 1985 BMW 318i. The master cylinder is a key component in your car's braking system, as it's responsible for converting the force you apply to the brake pedal into hydraulic pressure that pushes the brake pads against the rotors.

This DFC master cylinder is built to meet the original specifications for your 318i, ensuring it fits right and functions as expected. It's a well-built replacement designed to get your braking system back to proper working order.
