Rear Brake Drum and Shoe Inspection

Brake Drum
Inspect brake drum for wear.
If drum inner diameter is exceeds the limit or uneven or
stepped wear is excessive, replace the drum.
Rear brake drum inner diameter "a"
Standard: 254 mm (10.00 in.)
Limit: 256 mm (10.07 in.)
Cracked, scored, or grooved drum
A cracked, drum is unsafe for further service and must
be replaced.
Do not attempt to weld a cracked drum.
Smooth up any slight scores. Heavy or extensive scoring
will cause excessive brake lining wear and it will
probably be necessary to resurface drum braking
surface.
If brake linings are slightly worn and drum is grooved,
drum should be polished with fine emery cloth but should
no be turned.
NOTE
When drum is removed, visually inspect
wheel cylinder for brake fluid leakage.
Correct leaky point, if any.
