Suzuki Grand Vitara JB627. Manual - part 178
4C-3 Rear Brakes:
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.
Brake Shoe
CAUTION
!
Never polish lining with sandpaper. If lining is
polished with sandpaper, hard particles of
sandpaper will be deposited in lining and
may damage drum. When it is required to
correct lining, replace it with a new one.
Measure the minimum thickness of brake lining (1). Also,
check surface of lining for hardening, excessive wear
and oil.
