Rear Brake Shoe On-Vehicle Inspection; Rear Brake Shoe Removal And Installation - Suzuki 2006 SX4 Service Manual

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 in the
direction of drum depth but not circumferentially along
drum inner.
NOTE
When drum is removed, visually inspect
wheel cylinder for brake fluid leakage.
Correct leaky point, if any.
Brake Shoe
Measure thickness of brake shoe (1). Also, check
surface of lining for hardening, excessive wear and oil.

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.
