Work ProcedureINFOID:0000000006216242
NOTE:
If “WRITE CONFIGURATION” is unsuccessful, perform “Accessory Number Initialization”. For details, refer to
AV-28, "
On Board Diagnosis Function".
After performing “Accessory Number Initialization”, reboot the AV control unit to perform “WRITE CONFIGU-
RATION”.
1.WRITING MODE SELECTION
CONSULT-III Configuration
Select “CONFIGURATION” of “MULTI AV”.

 Never deform the pad retainer when removing the pad retainers (2) from the torque member (1).
 Never damage the piston boot.
 Never drop the brake pads, shims and shim covers.
 Remember each position of the removed brake pads.
5. Perform inspection after removal. Refer to BR-36, "
BRAKE PAD
: Inspection".
INSTALLATION
WARNING:
Clean any dust from the brake caliper assembly an d brake pads with a vacuum dust collector. Never
blow with compressed air.
CAUTION:
 Never depress the brake pedal while removing th e brake pads because the piston may pop out.
 If the brake fluid or grease adheres to the brake cal iper assembly and disc rotor, quickly wipe it off.
1. Install the torque member if the pad retainers has been removed. CAUTION:
 Securely assemble the pad retainers (1) so that it will notbe lifted up from the torque member (2).
 Never deform the pad retainers.
2. Apply MOLYKOTE
® AS880N or silicone-based grease mating
faces (A and B) between the brake pad, shim and shim cover,
and install shim and shim cover to the brake pad.
CAUTION:
Always replace the shims and shim covers when replacing
the brake pad.
3. Install the brake pads to the torque member.
4. Install pad return springs (1). CAUTION:
Correctly insert the pad return spring into the pad return
spring hole on the brake pad.
5. Install cylinder body to torque member. CAUTION:
 Never damage the piston boot.
 When replacing brake pad with new one, check a brakefluid level in the reservoir tank because brake fluid
returns to reservoir tank when pressing piston in.
NOTE:
Use a disc brake piston tool to easily press piston.
6. Install lower sliding bolt and tighter it to the specified torque.

2. Apply rubber grease to piston seals (1), and install them to cali- per.
CAUTION:
Never reuse piston seals.
3. Apply rubber grease to piston boots (1). Cover the piston (2) end with piston boot, and then install cylinder side lip on piston boots
securely into a groove on cylinder body.
CAUTION:
Never reuse piston boots.
4. Apply new brake fluid to pistons (1). Push piston into cylinder body by hand and push piston boots (2) piston-side lip into the
piston groove.
CAUTION:
Press the pistons evenly and var y the pressing point to pre-
vent cylinder inner wall from being rubbed.
5. Apply rubber grease to sliding pin boots, and install sliding pin boots to torque member.
6. Apply rubber grease to sliding pin, and install the cylinder body.
7. Install sliding pin bolts and tighten it to the specified torque. Refer to BR-34, "
