Rear Brake

BRAKE (REAR): REAR BRAKE: INSPECTION

1. INSPECT BRAKE CYLINDER AND PISTON

(a) Inspect the cylinder bore and the piston for rust or scoring. If necessary, replace the rear disc brake cylinder assembly and piston.

2. INSPECT PAD LINING THICKNESS

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

Standard thickness:

10.5 mm (0.413 in.)

Minimum thickness:

1.0 mm (0.0394 in.)

(b) If the pad lining thickness is less than the minimum, replace the brake pads.

HINT
Be sure to check rear disc thickness after replacing the brake pads with new ones.

3. INSPECT REAR DISC BRAKE PAD SUPPORT PLATE

(a) Make sure that the rear disc brake pad support plates have sufficient rebound, no deformation, cracks or wear, and that all rust and dirt are removed. If necessary, replace the rear disc brake pad support plates.

4. INSPECT DISC THICKNESS

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

Standard thickness:

12.0 mm (0.472 in.)

Minimum thickness:

10.5 mm (0.413 in.)

(b) If the disc thickness is less than the minimum, replace the rear disc.

5. INSPECT DISC RUNOUT

(a) Inspect the rear axle hub bearing looseness Rear Axle Hub.

(b) Using SST to hold the rear disc, tighten the rear disc with the 5 hub nuts.

SST : 09330-00021





Torque : 103 Nm (1050 kgf-cm, 76 ft-lbf)

(c) Using a dial indicator, measure the disc runout 10 mm (0.394 in.) away from the outer edge of the rear disc.

Maximum disc runout:

0.15 mm (0.00591 in.)

NOTICE:
Keep the magnet of the dial indicator away from the axle hub and speed sensor.

HINT
If the runout exceeds the maximum value, change the installation position of the disc to minimize the runout. If the runout exceeds the maximum even when the installation position is changed, grind the disc. If the disc thickness is less than the minimum, replace the rear disc.

(d) Remove the 5 hub nuts and the rear disc.
