Master Cylinder
The master cylinder is the heart of your braking system, turning the push of your brake pedal into the hydraulic pressure that stops your car. When it fails, your pedal can feel soft, sink to the floor, or lose braking power. We test, repair, or replace your master cylinder and bleed the brakes so you can stop with full confidence.

Frequently asked questions
How do I know if my master cylinder is failing?
The most common signs are a brake pedal that feels soft or slowly sinks to the floor, a sudden loss of braking power, or brake fluid leaking near the firewall. If you notice any of these, have it checked right away, as it affects your ability to stop safely.
Do you bleed the brakes after replacing the master cylinder?
Yes. Bleeding the brakes is an essential part of the job to remove any air from the lines. We always test and bleed the system afterward so your pedal feels firm and your brakes respond properly.
