Rear Brake

BRAKE (REAR): REAR BRAKE: INSPECTION

1. CHECK PAD LINING THICKNESS





(a) Using a ruler, measure the pad lining thickness.

Standard Thickness:

12.0 mm (0.472 in.)

Minimum Thickness:

1.0 mm (0.0394 in.)

If the pad lining thickness is less than the minimum, replace the pad.

HINT
Be sure to check the wear on the rear disc after replacing the brake pad with a new one.

2. CHECK DISC THICKNESS

(a) Temporarily install the disc with 3 hub nuts.

(b) Using a micrometer, measure the disc thickness.





Standard Thickness:

18.0 mm (0.709 in.)

Minimum Thickness:

16.0 mm (0.630 in.)

If the disc thickness is less than the minimum, replace the disc.

3. CHECK DISC RUNOUT

(a) Fix the disc in place with the 5 hub nuts.

Torque : 131 Nm (1336 kgf-cm, 97 ft-lbf)

(b) Using a dial indicator, measure the disc runout at a position 10 mm (0.394 in.) from the outside edge.





Maximum Disc Runout:

0.15 mm (0.00590 in.)

If the disc runout is more than the maximum, check the rear axle shaft Rear Axle Shaft. If the rear axle shaft is normal, adjust the disc runout or grind the disc on an on-vehicle brake lathe.

4. ADJUST DISC RUNOUT

(a) Remove the 2 bolts and rear disc brake cylinder mounting from the backing plate.

(b) Remove the hub nuts and disc. Rotate the disc 1/5 of a turn from its original position on the hub, and install the disc with the hub nuts.

Torque : 131 Nm (1336 kgf-cm, 97 ft-lbf)

(c) Measure the disc runout. Make a note of the runout and the disc position on the hub.

(d) Repeat the 2 previous steps until the disc has been installed on the 3 remaining hub positions.

If the minimum runout recorded above is less than 0.15 mm (0.00590 in.), install the disc in the position with the smallest runout. If the minimum runout recorded above is more than 0.15 mm (0.00590 in.), replace the disc and repeat the "Check Disc Runout" procedure.
