Presentation Transcript

  1. DISC BRAKE SERVICE • Review parts & operation of disc brakes • Complete brake inspection • Brake job disc brakes • Machine rotors • Pack wheel bearings

  2. Review of Basics • In terms of energy what do brakes do? • Convert mechanical energy to heat energy. • Why are disc brakes better than drum brakes? • Disc brakes dissipate heat more efficiently. • Which does more braking? A braked turning wheel or a braked locked-up wheel? • Braking only occurs when the wheel are turning,

  3. Disc Brake Parts • Rotor • Caliper • Brake pads • Piston • Square cut seal • Dust boot • Guide pins • Mounting bracket

  4. Inspecting Disc Brakes • Road test and function checks • Shop tests • Disc brake pad thickness • Inspection of rotor. (Miking)

  5. Pulsation Brake Pull Brake Lock-up Spongy Pedal Drag Fade Scraping Squeal Grinding Clunk Vibration Road Test

  6. Shop InspectionCaliper, Pads, Rotor & Hardware • Inspect brake hose for cracks. • Inspect the brake pads for there thickness. The pad material should be at least as thick as the backing plate. • Look for any damage to the mis. hardware. • Mike the rotor.

  7. Micrometer

  8. Disc Brake Service • Disassembly and Removal of Caliper • C-Clamp • Inspection of Hardware • Replacing Pads • Disc Brake Quiet • Reassembly

  9. Machining Rotors • A limited amount of metal can removed from the rotor because of heat dissipation. • Thickness of rotor new. • Machine to thickness. • Discard thickness.

  10. Machining Rotors • Measuring rotor thickness • Mounting on lathe • Scratch cut • Coarse Cut(s) .006” • Fine Cut .004” • Cleaning hub

  11. Removing the Rotor

  12. Mounting on the Lathe

  13. Cleaning Wheel Bearings

  14. Installing New Oil Seal

  15. Installing the Rotor
