What does a brake master cylinder do?

The master cylinder is the heart of your car's hydraulic braking system. When you press the brake pedal, it pushes fluid through the brake lines to activate the calipers or wheel cylinders, which then apply pressure to stop your vehicle.

What are the symptoms of a failing brake master cylinder?

Common signs include a spongy or soft brake pedal, a brake pedal that sinks to the floor, a low brake fluid level, or visible leaks around the master cylinder itself. You might also notice your car pulling to one side when braking.

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 1969 or 1970 Cadillac Eldorado, 1970 Buick Riviera, or 1970 Buick Wildcat. It's designed to be a direct fit, meaning it should install without needing any modifications to your existing brake lines or mounting points.

A properly functioning master cylinder is crucial for your car's braking system. It's the component that converts the force you apply to the brake pedal into hydraulic pressure that forces your brake pads or shoes against the rotors or drums. If your old master cylinder is leaking, or if you're experiencing a spongy brake pedal, replacing it with a new one like this DFC unit can restore your car's stopping ability. This part is made to meet the original specifications for your vehicle, helping to ensure consistent performance.
