What does a brake master cylinder do?

The brake master cylinder converts the force you apply to the brake pedal into hydraulic pressure. This pressure is then sent through your brake lines to activate the brakes at each wheel, allowing your vehicle to slow down or stop.

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

Common signs include a spongy or soft brake pedal, a brake pedal that sinks to the floor when held, a visible fluid leak from the master cylinder itself, or a warning light on your dashboard indicating low brake fluid or 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, part number 355-46007, is built to replace the original unit on a range of GM vehicles from the late 1980s and early 1990s. If your current master cylinder is leaking fluid or you're experiencing a spongy brake pedal, this part is designed to restore proper braking function. It's a direct fit replacement, meaning it bolts up where the original did, simplifying the installation process.

DFC has manufactured this master cylinder to meet the original specifications for vehicles like the Buick Reatta, Buick Riviera, and Cadillac DeVille. A properly functioning master cylinder is crucial for your braking system; it's the component that converts the force from your brake pedal into hydraulic pressure that pushes the brake pads against the rotors. When this part wears out, it can lead to reduced stopping power and a less responsive pedal feel. This unit is well-built to ensure reliable performance for your daily driving needs.

When replacing your master cylinder, it's a good practice to also inspect your brake lines for any signs of corrosion or damage. You'll also want to bleed your brake system thoroughly after installation to remove any air and ensure optimal braking performance. This DFC master cylinder is a solid option for getting your braking system back in top shape.
