< 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 

BR-7, "Inspection and

Adjustment"

.

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.

REAR DISC BRAKE

4.

Apply brake fluid to piston (1). Push piston into cylinder body by
hand and push piston boot (2) piston side lip into the piston
groove.

CAUTION:

Press the piston evenly and vary the pressing point to pre-
vent cylinder inner wall from being rubbed.

5.

Apply rubber grease to bushing, and install bushing to sliding pin
bolt.

6.

Apply rubber grease to the sliding pin bolts and the sliding pin
boots, install sliding pin boots to torque member.

7.

Install the cylinder body to the torque member and tighten the
sliding pin bolts to the specified torque. Refer to 

BR-39, "BRAKE

PAD : Exploded View"

BRAKE CALIPER ASSEMBLY : Inspection

INFOID:0000000006940188

INSPECTION AFTER DISASSEMBLY

Cylinder Body

Check the inner wall of the cylinder for rust, wear, cracks or damage. Replace the cylinder if any abnormal
condition is detected.

CAUTION:

Always clean with new brake fluid. Never clean with mineral oil such as gasoline and light oil.

Torque Member

Check the torque member for rust, wear, cracks or damage. Replace the member if any abnormal condition is
detected.

Piston

Check the piston for rust, wear, cracks or damage. Replace the piston if any abnormal condition is detected.

CAUTION:

A piston sliding surface is plated. Never polish with sandpaper.

Sliding Pin Bolt and Sliding Pin Boot

Check the sliding pin bolts and sliding pin boots for rust, wear, cracks or damage. Replace the parts if any
abnormal condition is detected.

INSPECTION AFTER INSTALLATION

1.

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

BR-

42, "BRAKE CALIPER ASSEMBLY : Disassembly and Assembly"

.

7.

Burnish contact surfaces after refinishing or replacing disc rotors, or if a soft pedal occurs at very low mile-
age. Refer to 

BR-16, "DISC ROTOR : Inspection and Adjustment"

.
