Our Services - Brake Service & Systems

The brake system is actually composed of two kinds of systems -- Hydraulics and Friction Systems. Here is a breakdown of what happens within these systems between the time your foot hits the peddle and your vehicle stops.

Master Cylinder

When pressure is applied to the brake pedal, the master cylinder creates hydraulic pressure which pushes brake fluid to the wheel brakes.

Brake Lines and Hoses
Steel brakes lines and high pressure rubber hoses are the avenues through which the pressurized brake fluid travels.

Wheel Cylinders and Calipers

These are the hydraulic cylinders that apply pressure to the friction materials, which stops your vehicle.

Friction Materials

Disc Brake Pads and Drum Brake Shoes
These brake linings are composed of high temperature materials that create the friction that stops your vehicle.

Disc Brakes
Disc brakes consists of a Disc Brake Rotor, which is attached to the wheel, and a Caliper, which holds the Disc Brake Pads. Hydraulic pressure from the Master Cylinder causes the Caliper Piston to clamp the Disc Brake Rotor between the Disc Brake Pads. This creates friction between the pads and rotor, causing your vehicle to slow down or stop.

Drum Brakes
Drum Brakes consist of a Brake Drum attached to the wheel, a Wheel Cyinder, Brake Shoes and Brake Return Springs. Hydraulic pressure from the Master Cylinder causes the Wheel Cylinder to press the Brake Shoes against the Brake Drum. This creates friction between the shoes and drum to slow or stop your vehicle.

Parking Brake
The Parking Brake uses cables to mechanically apply the brakes, usually the rear brake. This is used to prevent the vehicle from rolling when not being driven.

Anit-Lock Brakes: A System Built For Safety
Computer-controlled anti-lock braking systems (ABS) are a recenly developed safety feature. When sudden stops are made, the ABS prevents wheel lock-up. The system is compised of wheel-speed sensors that monitor wheel rotation, computer-controlled hydrualics that pulse the brakes on and off rapidly, and thhe on-board computer.
