3. Partially drain the brake fluid. Refer to 

BR-20, "Drain and Refill"

.

4. Remove lower sliding pin bolt using power tool and swing the caliper body up to access the brake pads.
5. Support the caliper body with a suitable wire to avoid pulling on the rear brake hose.
6. Remove the rear inner and outer brake pads, shims and retainers from the torque member.

INSTALLATION

1. Attach shims to the brake pads.
2. Apply Molykote 7439 grease (A) to the pad retainers as shown.

3. Attach pad retainer to torque member, then install brake pad and

shim assemblies.

CAUTION:

When attaching pad retainer, attach it firmly so that it is

flush with torque member, as shown.

4. Using a suitable tool push piston into caliper body.

CAUTION:

By pushing in piston, brake fluid returns to master cylinder reservoir tank. Watch the level of the

brake fluid in reservoir tank.

NOTE:

Use a suitable tool to make it easier to push the piston into the caliper body.

5. Remove the suitable wire then swing the caliper body down over the brake pad assemblies.
6. Install the lower sliding pin bolt and tighten to specification. Refer to 

BR-48, "Exploded View of Brake Cal-

iper"

.

7. Check the brakes for drag.
8. Inspect the brake fluid level and refill if necessary. Refer to 

BR-20, "Drain and Refill"

. 

9. Install the rear wheel and tire. Refer to 

WT-50, "Adjustment"

.

Brake Burnishing

INFOID:0000000006245731

Burnish brake contact surface according to the following procedure after refinishing or replacing rotors, after

replacing pads, or if a soft pedal occurs at very low mileage.

CAUTION:

Only perform this procedure under safe road and traffic conditions. Use extreme caution.

1. Drive the vehicle on a straight smooth road at 50 km/h (31 MPH). 
2. Use medium brake pedal/foot effort to bring the vehicle to a complete stop from 50 km/h (31 MPH). Adjust

brake pedal/foot pressure such that vehicle stopping time equals 3 to 5 seconds.   

3. To cool brake system, drive the vehicle at 50 km/h (31 MPH) for 1 minute without stopping.
4. Repeat steps 1 to 3, 10 times or more to complete the burnishing procedure.

WARNING:

Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of airborne

particles or other materials.

CAUTION:

• While removing caliper body never depress brake pedal because piston will pop out. 

• It is not necessary to remove bolts on torque member and brake hose except for disassembly or

replacement of caliper body. In this case, hang caliper body with a wire so as not to stretch the brake

hose.

• Do not damage the piston boot.

• If any shim is subject to serious corrosion, replace it with a new one.

• Always replace shim and shim cover as a set when replacing brake pads.

• Keep rotor free from grease and brake fluid.

• Burnish the brake contact surface after refinishing or replacing rotors, after replacing pads, or if a

soft pedal occurs at very low mileage. Refer to 

BR-47, "Brake Burnishing"

.

3. Remove the union bolt then disconnect the brake hose and dis-

card the copper sealing washers.

CAUTION:

Do not reuse copper sealing washers.

4. Remove the sliding pin bolts and remove the caliper body from

torque member.

5. Remove the brake pads, shims and retainers from the torque member.
6. Remove the torque member bolts and remove the torque member.
7. Remove the disc rotor. If reusing the disc rotor, apply a matching

mark as shown for installation.

CAUTION:

Put matching marks on the wheel hub assembly and disc

rotor, if reusing the disc rotor.

INSTALLATION

1. Install the disc rotor. If reusing the disc rotor, align the matching

marks as shown for installation.

CAUTION:
