Braking System

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:
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.

Hydraulics

Master Cylinder

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

Wheel Cylinders and Calipers

These are the hydraulic cylinders that apply pressure to the friction materials, causing your car to stop.

Anti-Lock Brakes: A System Built For Safety

Computer-controlled anti-lock braking systems (ABS) are a recently developed safety feature. When sudden stops are made, the ABS prevents wheel lock-up. The system is comprised of wheel-speed sensors that monitor wheel rotation, computer-controlled hydraulics that pulse the brakes on and off rapidly, and the on-board computer.

Disc Brakes

Drum Brakes

  • Disc brake rotors
  • Disc brake pads
  • Calipers
  • Caliper hardware
  • Brake drums
  • Brake shoes
  • Wheel cylinders
  • Return springs & hardware

Hydraulic System

Parking Brake

  • Master cylinder
  • Brake fluid
  • Brake hoses/lines
  • Power booster
  • Cables
  • Adjustment

Brake Lines and Hoses

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

Types of Brakes

Disc 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

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

Parking Brake

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.
