REMOVAL

1. Disconnect the vacuum hose from the brake booster.
2. Disconnect the vacuum hose from the intake manifold.
3. Release the clips and remove the vacuum pipe with the vacuum hoses attached.
4. Remove the vacuum hoses from the vacuum pipe.

INSPECTION AFTER REMOVAL

Visual Inspection

Check for correct installation, damage and deterioration of the vacuum hoses and pipe.

Valve Air-tightness Check

• Connect a suitable tool (hand vacuum pump) at each end of the vacuum hose to inspect the check valve

operation.

• Replace the vacuum hose component or check valve if out of specification.

INSTALLATION

Installation is in the reverse order of removal.

• Because the vacuum hose contains a check valve, the vac-

uum hose must be installed in the correct position for proper

operation. Refer to the stamp on the end of the vacuum hose

to confirm correct installation. The brake booster will not

operate normally if the vacuum hose with the check valve is

installed in the wrong direction. 

• Insert the vacuum pipe into the vacuum hose at least 24 mm

(0.94 in) as shown.

• Do not use lubricating oil during installation.

Removal and Installation of Brake Pads

INFOID:0000000009466602

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 brake pads, 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. For brake pad removal, hang cylinder body 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 and pads free from grease and brake fluid.

• Burnish the brake pads and disc rotor contacting surfaces, after refinishing or replacing rotors, after

replacing pads, or if a soft pedal occurs at very low mileage. Refer to 

BR-31, "Brake Burnishing Pro-

cedure"

.

2. Partially drain brake fluid from master cylinder.
3. Remove the upper and lower sliding pin bolts.

NOTE:

Note the sliding 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. 

5. Remove anti-rattle clips, pads, shims, and shim covers from torque member.

INSTALLATION

1. Apply Molykote AS-880N grease or equivalent between the inner and outer shims and the back of the

brake pads.

2. Install the inner and outer shims and shim covers to the inner pad and outer pad.

CAUTION:

Do not get grease on the inner and outer pad friction surfaces.

3. Apply Molykote 7439 grease (A) or equivalent to the pad

retainer and attach the pad retainer to the torque member.

4. Install the assembled inner and outer shims, shim covers, pads

and anti-rattle clips to the torque member.

CAUTION:

Do not get grease on the inner and outer pad or rotor fric-

tion surfaces.

5. Press piston into cylinder body using suitable tool, then install

the cylinder body on the torque member.

CAUTION:

When replacing pads with new set, check the brake fluid

level in the reservoir tank because brake fluid returns to the

master cylinder reservoir tank when pressing in the piston.

6. Install the upper and lower sliding pin bolts (2) and tighten it to

the specified torque.

• Union bolt (1)

7. Check front disc brakes for drag.
8. Install the front wheel and tire. Refer to 

WT-60, "Adjustment"

.

9. Check brake fluid level and refill as necessary. Refer to 

BR-16, "Inspection"

.

Brake Burnishing Procedure

INFOID:0000000009466603

Burnish contact surfaces between disc rotors and pads according to following procedure after refinishing or

replacing rotors, after replacing pads, or if a soft pedal occurs at very low mileage.

CAUTION:

• Be careful of vehicle speed because the brake does not operate easily until pad and disc rotor are

securely fitted.

• Only perform this procedure under safe road and traffic conditions. Use extreme caution.

1. Drive vehicle on straight, flat road. 

2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.

3. Drive without depressing brake for a few minutes to cool the brake.

4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.
