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. (For

both side of vacuum hose of intake manifold side.)

- Face the marking side vehicle front when assembling of vacuum

hose. (For both side of vacuum hose of brake booster side)

CAUTION:

Never use lubricating oil during assembly.

• Use a handy vacuum pump (A) to check.

• Replace vacuum hose assembly if vacuum hose and check valve

are malfunctioning.

When connected to the brake booster side (B)

: Vacuum should decrease within 1.3 kPa (10 mmHg, 
0.39 inHg, 0.013 bar) for 15 seconds under a vacuum 
of 

−

REMOVAL

WARNING:

Clean any dust from the brake caliper and brake pads with a vacuum dust collector. Never blow with
compressed air.

CAUTION:

• Never depress the brake pedal while removing the brake pads because the piston may pop out.
• Never spill or splash brake fluid on the disc rotor.

1.

Remove tires.

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 and shim cover from the torque member.

CAUTION:

• Never deform the pad retainer when removing the pad retainer from the torque member. 
• Never damage the piston boot.
• Never drop the brake pads, shims, and the shim cover.

INSTALLATION

WARNING:

Clean any dust from the brake caliper and brake pads with a vacuum dust collector. Never blow with
compressed air.

CAUTION:

• Never depress the brake pedal while removing the brake pads or the cylinder body because the pis-

ton may pop out.

• Never spill or splash brake fluid on the disc rotor.

FRONT DISC BRAKE

1.

Install the pad retainer to the torque member if the pad retainers has been removed.

CAUTION:

• Securely assemble the pad retainers so that it will not be lifted up from the torque member.
• Never deform the pad retainers.

2.

Apply copper based brake grease to the mating faces between the brake pads and pad retainers.

3.

Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease to the mating faces between the brake
pads, shims and shim cover, and install them to the brake pad.

CAUTION:

Always replace the shims together with the shim cover when replacing the brake pad.

4.

Install the cylinder body and brake pads to the torque member.

CAUTION:

• Never damage the piston boot.
• When replacing a pad with new one, check a brake fluid level in the reservoir tank because brake

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

NOTE:
Use a disc brake piston tool to easily press piston. 

5.

Install the lower sliding pin bolt and tighten it to the specified torque.

6.

Depress the brake pedal several times to check that no drag feel is present for the front disc brake. Refer
to 

BR-34, "BRAKE PAD : Inspection"

.

INSPECTION AFTER REMOVAL

Replace the shims and the shim cover if rust is excessively attached.

INSPECTION AFTER INSTALLATION

1.

Check a drag of front disc brake. If any drag is found, follow the procedure described below.

2.

Remove brake pads.

3.

Press the piston.

CAUTION:

• Never damage the piston boot.
• When replacing a pad with new one, check a brake fluid level in the reservoir tank because brake

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

NOTE:
Use a disc brake piston tool to easily press piston.

4.

Install brake pads.

5.

Depress the brake pedal several times.

6.

Check a drag of front disc brake again. If any drag is found, disassemble the cylinder body. Refer to 

BR-

36, "BRAKE CALIPER ASSEMBLY : Disassembly and Assembly"

.

7.

Burnish contact surfaces after refinishing or replacing pads, or if a soft pedal occurs at very low mileage.
Refer to 

BR-13, "BRAKE PAD : Inspection and Adjustment"
