a) Remove the brake drums.
b) Check the thickness of the brake linings/pads.
Nominal thickness:
- left hand drive models - 4.5 mm
right hand drive models:
- 2WD - 4.3 mm
- 4WD - 4.5 mm
Minimum overlay thickness:
- left hand drive models - 2.0 mm
- right hand drive models - 1.0 mm
Replace brake pads if necessary.
Note: Replace brake pads as a set (right and left sides at the same time) if any of the pad linings is of minimum or lesser thickness.
2. Checking the brake drum.
a) Measure the inner diameter of the brake drum.
Nominal diameter:
- left-hand drive models - 199.9 - 200.0 mm
right hand drive models:
- 2WD - 180.0 mm
- 4WD - 200.0 mm
Maximum allowable diameter:
- left-hand drive models - 201 mm
right hand drive models:
- 2WD - 181 mm
- 4WD - 201 mm
b) Check the inner surface of the drum for cracks, unevenness and uneven surface wear.
c) If necessary, repair or replace the drum. Drums with only minor defects can be repaired.
d) When repairing or replacing the drum, check the tightness of the brake shoes. Apply chalk to the working surface of the drum and check the tightness of the shoes.
Caution: Remove chalk from drum and shoe surface after checking.
