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.
