What Our ASE Certified Technicians Do
The following components are inspected. Their condition is recorded and compared to manufacturer's specs. Recommendations are made per the Motorist Assurance Program Uniform Inspection Guidelines
Heating and Air Conditioning Systems
Heating and Air Conditioning Tests
The brake system is actually composed of two kinds of systems---Hydraulics and Friction Materials. Here's what happens within these systems between the time your foot hits the brake pedal and your car stops.
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 brake 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, causing your car to stop.
Disc Brake Pads and Drum Brake Shoes
These brake linings are composed of high temperature materials that create the friction that stops your car.
Types of Brakes
Disc brakes consist 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 car to slow down or stop.
Drum brakes consist of a Brake Drum attached to the wheel, a Wheel Cylinder, 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 car.
The Parking Brake uses Cables to mechanically apply the brakes (usually the rear brake.) This is used to prevent the car from rolling when not being driven.
