< REMOVAL AND INSTALLATION >
BRAKE BOOSTER
• Idle the engine for 1 minute to apply vacuum to the brake booster,
and stop the engine. Then depress the brake pedal several times
at 5-second intervals until the accumulated vacuum is released to
atmospheric pressure. Check that the clearance between brake
pedal and dash lower panel gradually increases (A
→
B
→
C) each
time the brake pedal is depressed during this operation.
• Depress the brake pedal with the engine running. Then stop the
engine while holding down the brake pedal. Check that the brake
pedal stroke does not change after holding down the brake pedal
for 30 seconds or more.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. This is a normal phenomenon due
to the brake system operation.
ADJUSTMENT AFTER INSTALLATION
Perform the brake pedal adjustment after installing the brake pedal assembly. Refer to
.

REMOVAL
Remove the vacuum hose and tube.
INSTALLATION
Note the following, install the vacuum hose and tube.
• Because vacuum hose contains a check valve, it must be installed in the correct position. Refer to the stamp
to confirm correct installation. Brake booster will not operate normally if the hose is installed in the wrong
direction.
• When installing vacuum hose, insert it until its tip reaches the
back-end of length (A) or further as shown in the figure.
- Face the marking side up when assembling of vacuum hose.
(Brake booster and intake manifold side)
- Face the marking side vehicle front when assembling of vacuum
hose. (Vacuum tube side)
CAUTION:
Never use lubricating oil during assembly.

REMOVAL
WARNING:
Since dust covering the front brake has an affect on human body, the dust must be removed with a
dust collector. Never splatter the dust with an air blow gun.
CAUTION:
• Never depress the brake pedal while removing the brake pads or cylinder body because the piston
may pop out.
• Never spill or splash brake fluid on the disc rotor.
1.
Remove tires with power tool.
2.
Remove lower sliding pin bolt.
3.
Suspend the cylinder body with suitable wire so that the brake hose will not stretch. Then remove the
brake pads, shims, shim covers and pad retainers from the torque member.
CAUTION:
• Never reuse the pad retainers when removed the pad retainers from the torque member.
• Never damage the pistons boots.
• Never drop the brake pads, shims, and the shim covers.
• Remember each position of the removed brake pads.
