Maximum Allowable Stock Removal
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1997 Ford Pickup, 1997 Ford F-Super Duty, 1997 Ford Cab & Chassis, 1996 Ford Pickup, and 1996 Ford F-Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
- To measure maximum allowable stock remaining for refinishing on inner rotor face, use Disc Rotor Surface Gauge And Ball (T71P-1102-A). See Fig 1. Remove inner grease seal and bearing from rotor. Wipe inner and outer bearing cups clean.
- Carefully place gauge ball in inner bearing cup. DO NOT drop. Set micrometer at base line setting number. Using a 2 1/8" (54 mm) gauge ball, base line setting is.256" (6.50 mm). Position micrometer gauge bar on inner rotor face with micrometer centered over gauge ball.
- To measure distance between micrometer base line setting and gauge ball, turn micrometer down to touch top of ball. Calculate difference between reading and base line setting; difference is maximum allowable stock which can be removed from inner rotor face.
- When micrometer is set at base line setting and micrometer end touches top of ball, no additional material may be removed from rotor. If micrometer must be retracted from base line setting to allow gauge bar legs to rest on rotor face, rotor has been refinished beyond allowable limit. Replace rotor.
