What You Should Know About Brake Master Cylinder Replacement

  • Master cylinder is the center of your car’s braking system
  • Utilizes the force of your foot on the brake pedal to engage the brakes
  • Warning signs include: Brake pedal feels spongy or goes to floor, brake fluid is leaking or looks dirty, your check engine or brake warning light comes on, car “weaves” when braking
  • Master cylinder failure could result in brake loss
  • See a mechanic immediately if you think you have a problem

The master cylinder is the heart of your car’s braking system. It converts the force of your foot on the brake pedal into hydraulic pressure, forcing fluid through the brake lines which, in turn, engages the brakes. The warning signs you might need to replace this essential component are: Your brake pedal feels spongy or goes to the floor, brake fluid is leaking or looks dirty, your check engine or brake warning light comes on, or your car “weaves” when braking. If your master cylinder fails, your brakes could fail. If you think you might have a problem, see a mechanic immediately.
