ALL SUNBIRD, PHOENIX, GRAND AM MODELS
"Please discard previous bulletin 85-5-5 due to this updated information."
All models of the Sunbird, Phoenix and Grand Am have had an outboard shoe that is held in position by clinching the tabs with a ball peen hammer. The object of peening is to tightly attach the shoe to the caliper to dampen out vibrations in the pad that can cause a squeal. Tightening the pad by reclinching can have a positive effect on squeal. To reclinch the shoe:
1. Pry on the rotor with a screwdriver to move the pad into the caliper. (Figure 1)
2. Have someone apply the brakes firmly.
3. Reclinch the shoe by peening the tab. (Figure 2)
However, this procedure is different than the manual's because it requires that the brakes be applied while peening, to hold the pad firmly in position.
To Reclinch Pad (only) T3142 .3 hrs. Each Additional Wheel Add: .2 hrs.
If Necessary to Replace or R & R Pads, Disc Brake (H0042) Add Condition: To Reclinch Pad (each) .1 hrs.
General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
