Materials selection-of-brake

  1. 1. Materials Selection of DiscBrake Pads
  2. 2. Operation of Disc Brakes•Brake pedal is depressedpushing fluid through thesystem•A piston is then forced out•Brake pads are forcedtogether•Friction between pads androtor cause the car to slowdown
  3. 3. Factors in Material Selection Coefficient of friction Heat fade Thermal expansion Hardness
  4. 4. Brake Pad MaterialsOrganic and Asbestos - healthissues, softer composition, low heatfade resistance, small range of useSemi-Metallic -40% metal by content wt(steel wool, iron,)hard surface, high frictionTowing, larger vehiclesLow heat concern, wears rotors fastestCeramicCeramic fibers, <15% metal by wt. Ct.High hardness, more advanced technologyHigh heat operation, less heat fadeLong life
