# BRAKE CALIPERS TO KNUCKLE CLEARANCE-REVISION

THE FRONT CALIPER TO KNUCKLE CLEARANCE GIVEN IN THE SERVICE MANUALS MAY BE MISINTERPRETED. THE INDICATOR CLEARANCE OF 0.13-0MM (0.005- 0.012 IN.) REPRESENTS A IDEAL CONDITION WHERE THE CALIPER IS CENTERED IN THE KNUCKLE OPENING. IN ACTUAL PRACTICE, BRAKING ACTION MOVES THE CALIPER AGAINST THE KNUCKLE WHICH MAY RESULT IN LITTLE OR NO CLEARANCE ON ONE END OF THE CALIPER/KNUCKLE ASSEMBLY. THE CLEARANCE AT EACH END OF THE CALIPER SHOULD BE MEASURED INDIVIDUALLY AND ADDED TOGETHER TO DETERMINE THE TOTAL CALIPER TO KNUCKLE CLEARANCE. THE TOTAL CLEARANCE SHOULD BE 0.26-0.60MM (0.010-0.024 IN.) REFERENCE SECTION 5 OF THE SHOP MANUAL.

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.
