BRAKE PAD : Removal and Installation

INFOID:0000000004212575

WARNING:

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

particles or other materials.

CAUTION:

• While removing caliper, do not 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 assembly. In this case, hang caliper with a wire so as not to stretch brake

hose.

• Do not damage 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 brake fluid.

• Burnish the brake pads and disc rotor mutually contacting surfaces, after refinishing or replacing

rotors, after replacing pads, or if a soft pedal occurs at very low mileage. Refer to 

BR-29, "BRAKE

PAD : Brake Burnishing Procedure"

.

2. Remove lower sliding pin bolt.

3. Hang caliper with a suitable wire, and remove pads, pad retain-

ers, shims, and shim cover from torque member.

CAUTION:

When removing the pad retainer from the torque member,

lift it in the direction indicated by the arrow as shown so

that it does not deform.

INSTALLATION

1. Apply Molykote M-77 grease or equivalent between the outer shim cover and shim; and the inner multilay-

ered shim and inner pad. Install outer shim, outer shim cover to outer pad, and inner multilayered shim to

inner pad.

2. Apply Molykote 7439 grease or equivalent between pad retain-

ers and pad ends. Install pad retainers and pads on torque

member.

CAUTION:

• Securely assemble pad retainers so that they are not

being lifted up from torque member.

• Both inner and outer pads have a pad return system on

the pad retainer. Install pad return lever securely to pad

wear sensor.

3. Install caliper over assembled pads on to the torque member.

CAUTION:

When replacing a pad with new one, check brake fluid level in the reservoir tank because brake

fluid returns to master cylinder reservoir tank when pressing in the piston.

NOTE:

Use a disc brake piston tool (commercial service tool) to easily press in the piston.

BRAKE PAD : Brake Burnishing Procedure

INFOID:0000000004212560

Burnish contact surfaces between disc rotors and pads according to following procedure after refinishing or

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

CAUTION:

• Be careful of vehicle speed because the brake does not operate easily until pad and disc rotor are

securely fitted.

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

1. Drive vehicle on straight, flat road. 

2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.

3. Drive without depressing brake for a few minutes to cool the brake.

4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.
