FRONT BRAKE CALIPER

MEASURE PAD LINING THICKNESS

Using a ruler, measure the pad lining thickness.

Standard thickness: 11.5 mm (0.453 in.)

Minimum thickness: 1.0 mm (0.039 in.)

Replace the pad if the thickness is less than the minimum (the

1.0 mm slit is no longer visible), or if it shows signs of uneven

MEASURE DISC THICKNESS

Using a micrometer, measure the disc thickness.

Standard thickness: 28.0 mm (1.102 in.)

Minimum thickness: 26.0 mm (1.024 in.)

Replace the disc if the thickness of the disc is at the minimum

or less. Replace the disc or grind it on a lathe if it is scored or

worn unevenly.

MEASURE DISC RUNOUT

Using a dial indicator, measure the disc runout at a position 10

mm (0.39 in.) from the outside edge.

Maximum disc runout: 0.07 mm (0.0028 in.)

If the runout is greater than the maximum, replace the disc or

grind it on an "On−Car" brake lathe.

Before measuring the runout, confirm that the front hub bearing

play is within specifications (see page SA−20).

IF NECESSARY, ADJUST DISC RUNOUT

Remove the hub nuts and disc. Reinstall the disc 1/6 of

a turn round from its original position on the hub. Install

and torque the hub nuts.

Torque: 113 N·m (1,150 kgf·cm, 83 ft·lbf)

Remeasure the disc runout. Make a note of the runout

and the disc's position on the hub.

Repeat (a) and (b) until the disc has been installed on the

4 remaining hub positions.

If the minimum runout recorded in (a) to (c) is less than the maxi-

mum disc runout, install the disc in that position.

If the minimum runout recorded in (a) to (c) is greater than the

maximum disc runout, replace the disc and repeat step 3.
