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. |

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. |
