Service Overview

The brake master cylinder is the heart of your vehicle's braking system. It converts the force from your foot pressing the brake pedal into hydraulic pressure that activates the brakes at each wheel. When you press the brake pedal, the master cylinder pushes brake fluid through the lines to the calipers or wheel cylinders, creating the friction needed to stop your vehicle.

A failing master cylinder can compromise your entire braking system, leading to dangerous situations on the road. Signs of a failing master cylinder include a spongy brake pedal, fluid leaks, or the pedal slowly sinking to the floor when held down. Our expert technicians can diagnose and replace your master cylinder to ensure your brakes function properly.
