• 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.
  
  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.
  
  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 car.
  
  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.
  
  
  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.
