DISC BRAKE SERVICE 1.Review parts & operation of disc brakes 2.Complete brake inspection 3.Brake job disc brakes 4.Machine rotors 5.Pack wheel bearings
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,
Disc Brake Parts Rotor Caliper Brake pads Piston Square cut seal Dust boot Guide pins Mounting bracket
Inspecting Disc Brakes Road test and function checks Shop tests Disc brake pad thickness Inspection of rotor. (Miking)
Shop Inspection Caliper, 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.
Disc Brake Service Disassembly and Removal of Caliper C-Clamp Inspection of Hardware Replacing Pads Disc Brake Quiet Reassembly
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.
