Rear
REAR DISC BRAKE PAD CHECK AND REPLACEMENT1. Check brake pad thickness through caliper body check port.
Standard value: 10.0 mm (0.39 inch)
Limit: 2.0 mm (0.08 inch)
CAUTION:
1. When the limit is exceeded, the brake pads on both the left and right wheels must be replaced as a set.
2. If there is a large difference in thickness between the pads on the right and left wheels, check the sliding portions of the caliper.
2. Loosen the parking brake cable (from the vehicle interior), and disconnect the parking brake end installed on the rear brake assembly.
3. Remove lock pin. Lift caliper assembly, slide the assembly toward the inside of the wheel well until separated from the lock pin. Support it with wires.
CAUTION: Do not wipe off special grease on lock pin or do not make it dirty.
3. Remove the clip and pull out the pad pin while holding the cross spring by hand.
4. Remove the following parts from caliper support.
1) Outer shim
2) Pad assembly
3) Pad & wear indicator assembly
4) Clip
5) Inner shim A
6) Inner shim B
7) Outer shim A
8) Outer shim B
Measurement Of The Sliding Resistance:
5. With the brake assembly removed, use a spring scale to measure the rotary sliding resistance of the hub in the forward direction.
Disengage the drive shaft and companion flange.
NOTE: Secure the disc to the hub with wheel nuts.
6. Securely attach the pad clip to the caliper support.
CAUTION: Do not deposit grease or other dirt on pad or brake disc friction surfaces.
7. Clean the piston and then using the special tool, push the piston into the cylinder (caliper).
8.
With care not to allow the piston boot to be wedged, lower the caliper assembly and fit the lock pin.
9. Start the engine, depress the brake pedal firmly two to three times and stop the engine.
10. Give the brake disc ten turns in the forward direction.
11. Using a spring scale, measure the rotary sliding resistance of the hub in the forward direction.
12. Obtain the drag force of the disc brake (the difference between the values measured in 11 and 5).
Standard value: 70 N (15.4 lbs.) or less
13. If the drag force of the brake exceeds the standard value, disassemble the piston and check for dirty or corroded piston sliding surface and deteriorated piston seal.
