Component Description

The disc brake system consists of the following components:

  1. Disc Brake Pads  - Applies mechanical output force (from hydraulic brake calipers) to friction surfaces of brake rotors.
  2. Disc Brake Rotors  - Uses mechanical output force applied to friction surfaces from disc brake pads to slow speed of tire and wheel assembly rotation.
  3. Disc Brake Pad Hardware  - Secures disc brake pads firmly in proper relationship to hydraulic brake calipers; enables sliding motion of brake pads when mechanical output force is applied.
  4. Disc Brake Caliper Hardware  - Provides mounting for hydraulic brake caliper, secures caliper firmly in proper relationship to caliper bracket; enables sliding motion of brake caliper to brake pads when mechanical output force is applied.
