REMOVAL
1. Disconnect the vacuum hose from the brake booster.
2. Disconnect the vacuum hose from the engine intake manifold.
3. Remove the vacuum hose.
INSTALLATION
Installation is in the reverse order of removal.
• Inspect the vacuum hose and one-way check valve before installation. Refer to
.
CAUTION:
• Because the vacuum hose contains a one-way check valve, the hose must be installed in the correct
position. Refer to the stamp on the hose to confirm the correct direction for installation. The brake
booster will not operate normally if the hose is installed in the wrong direction.
• Do not use lubricating oil during assembly.

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
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.
