FEB., 1985
Subject: BRAKE CALIPERS TO KNUCKLE CLEARANCE
Model and Year: ALL
TO: ALL CHEVROLET DEALERS
The front caliper to knuckle clearance given in the service manuals may be misinterpreted. The indicator clearance of 0.13 - 0.30 mm (0.005 - 0.012 in.)
represents an 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 - 0.60 mm (0.010 -
0.024 in.). Reference Section 5 of the Shop Manual.
