Rear Drum Brakes & Shoes: Inspection
NOTE:
If shoe replacement is necessary, replace both right and left shoes to prevent car from pulling to one side during braking.
- Measure wear of brake lining at most worn area. Minimum thickness is .039" (1.0 mm). If thickness is less than .039" (1.0 mm), replace shoe and lining assembly. If there is a significant difference in brake lining thicknesses between right and left shoe, inspect wheel cylinder piston.
- Measure inside diameter of hub and drum at 2 or more locations. Minimum diameter is 9.0" (230.6 mm). If diameter is less than 9.0" (230.6 mm) or is badly out of balance, replace brake drum and shoe and lining assembly.
