• While removing cylinder 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 cylinder body. In this case, hang cylinder body with a wire so as not to stretch brake
hose.

• Do not damage piston boot.
• Burnish brake contact surface after refinishing or replacing rotors, after replacing pads, or if a soft

pedal occurs at very low mileage. Refer to 

BR-27, "Brake Burnishing"

.

Removal and Installation of Brake Pad

INFOID:0000000001297475

REMOVAL

1.

Remove wheel and tire using power tool.

2.

Remove master cylinder reservoir cap.

3.

Remove lower sliding pin bolt using power tool.

4.

Suspend cylinder body with a wire and remove pad return spring, pads, shim, shim covers, and retainers
from torque member.

INSTALLATION

1.

Apply Molykote M-77 grease between outer brake pad plate and shim, then attach shim and shim covers
to brake pads. Refer to 

MA-10, "Fluids and Lubricants"

.

2.

Attach pad retainer to torque member, then install brake pad,
shims and pad return spring.

CAUTION:

When attaching pad retainer, attach it firmly so that it is
flush with torque member, as shown.

3.

Using a suitable tool push pistons into cylinder body.
NOTE:
Using a disc brake piston tool (commercial service tool), etc.,
makes it easier to push pistons into cylinder body.

CAUTION:

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

4.

Remove wire then swing cylinder body down over brake pad assemblies.

5.

Install lower sliding pin bolt and tighten to specification. Refer to 

BR-10, "Component"

.

6.

Check brake for drag.

7.

Inspect fluid level, then install master cylinder reservoir cap.

8.

Install wheel and tire. Refer to 

WT-36, "Rotation"

.

Brake Burnishing

INFOID:0000000001297656

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.
