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 BR-33, "Inspection After
Removal".
CAUTION:
• Because the vacuum hose contains a one-way check val ve, the hose must be installed in the correct
position. Refer to the stamp on the hose to confi rm the correct direction for installation. The brake
booster will not operate normally if the ho se is installed in the wrong direction.
• Do not use lubricating oil during assembly.
• Insert the vacuum hose at least 24 mm (0.94 in) onto the brake booster fitting as shown.

WARNING:
Clean dust on brake calipers and brake pads with a vacuum dust collector to minimize the hazard of
airborne particles or other materials.
CAUTION:
• While removing brake caliper, do not depr ess brake pedal because piston will pop out.
• It is not necessary to remove bolts from torque member and brake hose except for disassembly or
replacement of brake caliper assembly. In this case, hang brake caliper with a wire so as not to
stretch brake hose.
• Do not damage piston boot.
• Keep brake rotor and brake pads free from brake fluid and grease.
• Burnish the brake pads and disc brake rotor mutual ly contacting surfaces after refinishing or replac-
ing disc brake rotors, after replacing brake pads, or if a soft pedal occurs at very low mileage. Refer
to BR-16, "Brake Burnishing"
.
REMOVAL
1. Partially drain brake fluid from the master cylinder. Refer to BR-14, "Drain and Refill".
2. Remove the front wheel and tire using power tool. Refer to WT-55, "Adjustment"
.

3. Remove upper and lower sliding pin bolts. Refer to BR-36,
"BRAKE CALIPER ASSEMBLY : Exploded View".
NOTE:
Note the pin orientation during removal. The lower sliding pin
contains a bushing.
4. Remove the brake caliper from the torque member. Leaving the brake hose attached, reposition the brake
caliper aside with wire.
CAUTION:
Do not twist or stretch brake hose.
5. Remove the brake pads, shims, and shim covers from the torque member.
6. Remove the brake pad retainers from the torque member. CAUTION:
When removing the brake pad retainers from the torque
member, lift it in the direct ion indicated by the arrow as
shown so that it does not deform.
INSTALLATION
Installation is in the reverse order of removal.
• Apply Molykote AS-880N grease or equivalent betw een the outer brake pad, outer shim cover and outer
shim and between the inner shim and inner brake pad. Inst all outer shim and outer shim cover to outer brake
pad. Install inner shim and inner shim cover to inner brake pad.
CAUTION:
• The inner shim cover (LH) (1) is different than the inner shim
cover (RH) (2). Install the i nner shim covers in the correct
position.
• Replace brake pad shims and covers as a set if any corro-
sion or damage exists.
• Apply Molykote 7439 grease or equivalent between brake pad retainers and brake pad ends. Install brake pad retainers and
brake pads to torque member.
CAUTION:
• Make sure the brake pad retainers are fastened properly to
the torque member.
• Replace brake pad retainers if damage exists.
• Press the piston into the cylinder bore of the caliper using a suitable tool.
• Check brake fluid level and refill as necessary. Refer to BR-8, "Inspection"
.
• Burnish contact surface between brake pads and disc brake rotors. Refer to BR-16, "Brake Burnishing"
.
