Braking Disc: Inspection
Before installing caliper assembly on vehicle, inspect braking disc. Mount dial indicator C-3339 on steering arm with plunger contacting disc approximately one inch from edge of disc. With wheel bearings adjusted to zero end play, lateral runout (both sides of disc) should not exceed.0025". If runout exceeds specifications, replace disc and hub assembly or reface disc.
NOTE:
When refacing disc, remove equal amounts from each side.
Thickness variation of disc should be measured at twelve equal points with a micrometer at a radius approximately one inch from edge of disc. If thickness measurements vary by more than.0005", disc should be refaced or a new disc and hub assembly installed. Light scoring and/or wear is acceptable. If heavy scoring or warping is evident, disc must be refaced or replaced. If cracks are evident, the disc and hub assembly must be replaced.
