Disassembly and Assembly

DISASSEMBLY





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





2. REMOVE PISTON
a. Put a piece of cloth or an equivalent between the piston and caliper.
b. Use compressed air to remove the piston from the cylinder.

CAUTION: Do not place your fingers in front of the piston when using compressed air.





3. REMOVE PISTON SEAL FROM CYLINDER
Using a screwdriver, remove the piston seal.
4. REMOVE 2 SLIDING BUSHINGS AND 3 DUST BOOTS

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 thickness or less, or if the pad has severe, uneven wear.





2. MEASURE DISC THICKNESS
Using a micrometer, measure the disc thickness.
Standard thickness: 9.0 mm (0.354 inch)
Minimum thickness: 7.5 mm (0.295 inch)
Replace the disc if the disc's thickness is at the minimum thickness or less. Replace the disc or grind it on a lathe if it is scored or worn unevenly.





3. MEASURE DISC RUNOUT
Using a dial indicator, measure disc runout at a position 10 mm (0.39 inch) from the outside edge.
Maximum disc runout: 0.15 mm (0.0059 inch)
If the disc's runout is at the maximum value or greater, check the bearing play is 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 grind it on a "On-car" brake lathe.
4. IF NECESSARY, ADJUST DISC RUNOUT
a. Remove the hub nuts and the disc. Reinstall the disc in the position turned 1/5 from its original position on the hub. Install and torque the hub nuts.
Torque: 103 Nm (1,050 kgf-cm, 76 ft. lbs.)
Remeasure the disc runout. Make a note of the runout and the disc's position on the hub.
b. Repeat (a) until the disc has been installed on the 3 remaining hub positions.
c. If the minimum runout recorded in (a) and (b) is less than 0.15 mm (0.0059 inch), install the disc in that position.
d. If the minimum runout recorded in (a) and (b) is greater than 0.15 mm (0.0059 inch), replace the disc and repeat step 3.

REASSEMBLY
Reassembly is in the reverse order of disassembly.
