CAUTION:

Because vacuum hose contains a check valve, it must be installed in the correct orientation. Refer
to the stamp or label to confirm correct installation. The brake booster will not operate normally if
the hose is installed in the wrong direction.

Insert the vacuum hose for at least 24 mm (0.94 in).

Do not use lubricating oil during assembly.

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 cylinder body, never depress the brake pedal because the piston will pop out.

It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of the caliper assembly. In this case, suspend cylinder body with 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 shims and shim covers as a set when replacing brake pads.

Burnish the brake contact surface after refinishing or replacing rotors, after replacing pads, or it a
soft pedal occurs at very low mileage. Refer to 

BR-32, "BRAKE BURNISHING PROCEDURE"

  .

NOTE:
Using a disc brake piston tool (commercial service tool), etc., makes it easier to push in the piston.

CAUTION:

By pushing in the piston, the brake fluid returns to the master cylinder reservoir tank. Watch the
level of the surface of the reservoir tank.

When attaching the pad retainer, attach it firmly so that it
does not float up higher than the torque member, as
shown in the figure.

any of the above conditions are observed, replace cylinder body.

Minor damage from rust or foreign materials may be eliminated by polishing surface with a fine
emery paper. Replace cylinder body if necessary.

Torque Member

Check for wear, cracks, and damage. If damage or deformation is present, replace the affected part.

Piston

CAUTION:

Piston sliding surface is plated, do not polish with emery paper even if rust of foreign materials
are stuck to sliding surface.

Check piston for score, rust, wear, damage or presence of foreign materials. Replace if any of the
above conditions are observed.

Check piston surface for corrosion, wear, and damage. If any non-standard condition is detected, replace
applicable part.

Sliding Pin, and Sliding Pin Boot

Check sliding pin and sliding pin boot for wear, damage, and cracks. If damage or deformation is present,
replace the applicable part.

replace applicable part.

Runout Inspection

1.

Using wheel nuts, fix disc rotor to the wheel hub. (2 or more positions)

2.

Check runout using a dial indicator. 
[measured at 10 mm (0.39 in) inside the disc edge]

NOTE:
Make sure that wheel bearing axial end play is with in the speci-
fications before measuring runout. Refer to 

FAX-5, "FRONT

WHEEL HUB AND KNUCKLE"

  .

3.

If runout still out of specification, turn rotor with on-car brake lathe (“MAD, DL-8700”, “AMMCO 700 and
705” or equivalent).

Thickness Inspection

Using a micrometer, check thickness of the disc rotor. If thickness is
outside the standard, replace disc rotor.

BRAKE BURNISHING PROCEDURE

Burnish the brake contact surface according to the following procedure after refinishing or replacing rotors,
after replacing pads, or if a soft pedal occurs at very low mileage.

CAUTION:

Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1.

Drive the vehicle on a straight smooth road at 50 km/h (31 MPH).

2.

Use medium brake pedal /foot effort to bring the vehicle to a complete stop from 50 km/h (31 MPH).
Adjust brake pedal /foot pressure such that vehicle stopping time equals 3 to 5 seconds.

3.

To cool the brake system, drive the vehicle at 50 km/h (31 MPH) for 1 minute without stopping.

4.

Repeat steps 1 to 3, 10 times or more to complete the burnishing procedure.

Standard thickness

: 28.0 mm (1.102 in)

Repair limit thickness

: 26.0 mm (1.024 in)

Use medium brake pedal /foot effort to bring the vehicle to a complete stop from 50 km/h (31 MPH).
Adjust brake pedal /foot pressure such that vehicle stopping time equals 3 to 5 seconds.

3.

To cool the brake system, drive the vehicle at 50 km/h (31 MPH) for 1 minute without stopping.
