1. 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 pad's thickness is at the minimum or if it shows signs of uneven wear.

2. MEASURE DISC THICKNESS

Using a micrometer, measure the disc thickness.

Using a micrometer, measure the disc thickness.

Standard thickness: 32.0 mm (1.260 in.) Minimum thickness: 30.0 mm (1.181 in.)

Replace the disc if the thickness of the disc is at the minimum thickness or less. Replace the disc or grind it on a lathe if it is scored or is worn unevenly.

3. MEASURE DISC RUNOUT

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

Using a dial indicator, measure the disc runout at a position 10 mm (0.39 in.) from the out side edge.

Maximum disc runout: 0.07 mm (0.0028 in.)

If the bearing play and axle hub runout are not abnormal, replace the disc or grind it on an "On-Car brake lathe".

HINT: Before measuring the runout, confirm that the front bearing preload is within the specification ( SA-16 ).

4. IF NECESSARY, REPLACE DISC

(a) Remove the front axle hub ( SA-12 ).

(a) Remove the front axle hub ( SA-12 ).

(b) Remove the disc from the axle hub (SA-13 ).

(c) Install a new disc and torque the 5 bolts.

Torque: 74 N·m (750 kgf·cm, 54 ft·lbf)

(d) Install the axle hub and adjust the front bearing preload ( SA-16 ).

INSTALLATION

Installation is in the reverse order of removal ( BR-19 ).

HINT:

  • After installation, fill the brake reservoir with brake fluid and bleed brake system ( BR-4 ).
  • Check for leaks.

REASSEMBLY

Reassembly is in the reverse order of disassembly ( BR-20 ).

HINT: Apply lithium soap base glycol grease to the parts indicated by the arrows ( BR-18 ).
