Front Brake

BRAKE (FRONT): FRONT BRAKE: INSPECTION

1. INSPECT BRAKE CYLINDER AND PISTON

(a) Check the cylinder bore and piston for rust and scoring. If necessary, replace the disc brake cylinder and piston.

2. INSPECT 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 thickness, replace the disc brake pads.

HINT
Be sure to check the wear of the front disc after replacing the brake pads with new ones.

3. INSPECT FRONT DISC BRAKE PAD SUPPORT PLATE

(a) Make sure that the disc brake pad support has sufficient rebound, no deformation, cracks or wear, and that all rust and dirt are cleaned off. If necessary, replace the disc brake pad support plate.

4. INSPECT DISC THICKNESS

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





Disc Thickness:





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

5. INSPECT DISC RUNOUT

(a) Using SST to hold the disc, tighten the disc with the 5 nuts.

SST : 09330-00021





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

(b) Inspect the front axle hub bearing looseness and front axle hub runout Front Axle Hub.

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





Maximum disc runout:

0.05 mm (0.00197 in.)

If the runout exceeds the maximum value, change the installation position of the disc to minimize 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 front disc.

(d) Remove the 5 nuts and front disc.
