Disassembly and Assembly

Rear:

DISASSEMBLY





1. REMOVE CYLINDER BOOT SET RING AND BOOT
Using a screwdriver, remove the cylinder boot set ring and cylinder boot from the cylinder.





2. REMOVE PISTON
a. Place a piece of cloth or similar article between the piston and caliper.
b. Use compressed air to remove the piston from the cylinder.

CAUTION: At the time of disassembly, please refer to the following item. Do not place your fingers in front of the piston when using compressed air.





3. REMOVE PISTON SEAL
Using a screwdriver, remove the piston seal from the cylinder.





4. REMOVE SLIDING PINS AND DUST BOOTS
a. Remove the 2 sliding pins from the torque plate.

NOTICE: At the time of reassembly, please refer to the following item. Insert the sliding pin with the sliding bushing into the bottom side.

b. Using a screwdriver and hammer, tap out the 2 dust boots.

HINT: At the time of installation, use a 21 mm socket and tap in 2 new dust boots into the torque plate.

NOTICE: At the time of reassembly, please refer to the following item.

Confirm that the metal plate portion of the dust boot fits correctly in the torque plate.

INSPECTION





1. MEASURE PAD LINING THICKNESS
Using a ruler, measure the pad lining thickness.
Standard thickness: 10.0 mm (0.394 inch)
Minimum thickness: 1.0 mm (0.039 inch)
Replace the pad if the pad's thickness is at the minimum or less, or if the pad has severe, uneven wear.
2. RIGHT WHEEL:
INSPECT BRAKE PAD WEAR INDICATOR





a. Disconnect the pad wear indicator connector from the speed sensor wire harness.





b. Check that continuity exists of pad wear indicator connector. If no continuity exists, replace the pad wear indicator.
c. Connect the connector to the speed sensor wire harness until the clicking sound can be heard.





3. MEASURE DISC THICKNESS
Using a micrometer, measure the disc thickness.
Standard thickness: 16.0 mm (0.630 inch)
Minimum thickness: 15.0 mm (0.591 inch)
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.
4. MEASURE DISC RUNOUT





a. Tighten the disc with the 3 hub nuts.

HINT: Using SST 09330-00021 to hold the disc during measurement.

Torque: 103 Nm (1,050 kgf-cm, 76 ft. lbs.)





b. Using a dial indicator, measure the disc runout at a position 10 mm (0.39 inch) from the out side edge.
Maximum disc runout: 0.05 mm (0.0020 inch)
If the disc's runout is at the maximum value or greater, check the bearing play in the axial direction and check the axle hub runout. If the bearing play and axle hub runout are not abnormal, adjust the disc runout or grid it on a "On-Car" brake lathe.
5. IF NECESSARY, ADJUST DISC
a. Remove the 2 bolts and torque plate.
b. Remove the 3 hub nuts, 2 screws and disc. Reinstall the disc 1/5 of a turn round from its original position on the hub. Install and torque the 3 hub nuts and 2 screws.

HINT: Use SST 09330-00021 to hold the disc during loosening/torquing the hub nuts.

Torque:
Hub nut 103 Nm (1,050 kgf-cm, 76 ft. lbs.)
Screw 5.4 Nm (55 kgf-cm, 48 inch lbs.)
c. Remeasure the disc runout. Make a note of the runout and the disc's position on the hub.
d. Repeat (b) until the disc has been installed on the 3 remaining hub positions.
^ If the minimum runout recorded in (b) and (c) is less than 0.05 mm (0.0020 inch), install the disc in that position.
^ If the minimum runout recorded in (b) and (c) is greater than 0.05 mm (0.0020 inch), replace the disc and repeat step 4.
e. Install the 2 bolts and torque plate.
Torque: 104 Nm (1,065 kgf-cm, 77 ft. lbs.)

REASSEMBLY
Reassembly is in the reverse order of disassembly.
