Brake Repair and Maintenance
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.
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 fromthe Master Cylinder causes the Caliper Piston to clamp the Disc BrakeRotor between the Disc Brake Pads. This creates friction between thepads 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 theMaster Cylinder causes the Wheel Cylinder to press the Brake Shoesagainst the Brake Drum. This creates friction between the shoes anddrum to slow or stop your car.
The Parking Brake uses Cables to mechanically apply the brakes (usually therear brake.) This is used to prevent the car from rolling when notbeing driven.
