Repair Procedures

Removal

1. 1
   Remove the wheel tire (A).

   Tightening torque: 107.9–128 N·m

   

2. 2
   Loosen the front brake caliper bolts.

   Tightening Torque: 21.6–31 N·m

   

3. 3
   Remove the pad return spring, and then separate the brake pad.

   

   

4. 4
   Loosen the caliper bolts, and then remove the caliper assembly.

   Tightening torque: 78.5–98 N·m

   

5. 5
   Loosen the screw and remove the front brake disc.

   Tightening torque: 4.9–5.9 N·m

   

Replacement

1. 1
   Remove the wheel tire (A).

   Tightening torque: 107.9–128 N·m

   

2. 2
   Loosen the guide rod bolt (B), and then rotate the caliper body (A) upward so that it does not interfere.

   Tightening Torque: 21.6–31 N·m

   

3. 3
   Remove the pad return spring, and then separate the brake pad.

   

   

Inspection

1. 1
   Inspect the brake pads for wear and discoloration.
2. 2
   Inspect the brake disc for damage and cracks.
3. 3
   Remove all rust and contamination from the surface, and measure the disc thickness at 8 points at equal distances (5 mm) from the outer edge of the brake disc. Front brake disc thickness - 13 inch Standard: 18.0 mm (0.7087 in.) - 13 Service Limit: 16.0 mm (0.6299 in.) - 14 inch Standard: 20.0 mm (0.7874 in.) - 14 Maximum Service Limit: 18.0 mm (0.7087 in.) - Runout: less than 0.005 mm (0.0002 in.)

   

4. 4
   If wear exceeds the limit, replace the discs and pads as a set on both the left and right sides of the vehicle.
5. 5
   Inspect the pad wear. Measure the pad thickness and replace it if it is less than the specified value. Pad thickness Standard: 11.0 mm (0.4331 in.) Maximum Service Limit: 2.0 mm (0.0787 in.)
6. 6
   Make sure grease is applied to the sliding contact points, and make sure the pad and backing plate are not damaged.

   

7. 7
   Position a dial indicator approximately 5 mm (0.2 in.) from the outer edge of the brake disc and measure the disc runout.

   Brake disc runout Limit: 0.04 mm (0.00157 in.) or less (new)

   

8. 8
   If brake disc runout exceeds the limit, replace the disc, then measure the runout again.
9. 9
   If the runout does not exceed the specification limit, install the brake disc by rotating it 180°, and then check the brake disc runout again.
10. 10
    If runout cannot be corrected by changing the brake disc position, replace the brake disc.

Installation

1. 1
   Install in the reverse order of removal.
2. 2
   Use SST (09581-11000) when installing the brake caliper assembly.

   

3. 3
   After installation, bleed the brake system. (Refer to Brake System — "Brake System")
