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 if a
soft pedal occurs at very low mileage. Refer to 

BR-32, "BRAKE BURNISHING PROCEDURE"

 .

Removal and Installation of Brake Pad

NFS000EF

REMOVAL

1.

Remove tires from vehicle with power tool.

2.

Remove lower sliding pin bolt.

3.

Suspend cylinder body with a wire, and remove the pads, shims
and shim covers from the torque member.

CAUTION:

When removing the pad retainer from the torque member,
lift the pad retainer in the arrow direction (shown in the fig-
ure) so as not to deform it.

INSTALLATION

1.

Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease to between inner pad and inner shim,

shim and outer shim cover to the outer pad.

2.

Push the piston in so that the pad is attached and then attach the cylinder body to the torque member.

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 sub-tank. Watch the level
of the surface of the sub-tank.

When installing the pad retainer, install it firmly so that it
does not float up from groove of the torque member, as
shown in the figure.

3.

Cylinder Body

CAUTION:

Use new brake fluid to clean. Do not use mineral oils such as gasoline or kerosene.

Check inside surface of cylinder for score, rust, wear, damage or presence of foreign materials. If
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.

DISC ROTOR INSPECTION
Visual Inspection

Check surface of the disc rotor for uneven wear, cracks, and serious damage. If any of them is detected,
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 gauge. [measured at 10 mm (0.39 in)
inside the disc edge]

NOTE:
Make sure that wheel bearing axial end play is within the specifi-
cations before measuring runout. Refer to 

FAX-6, "FRONT

WHEEL HUB AND KNUCKLE"

 .

3.

If runout is outside the limit, find the minimum runout point by
shifting mounting positions of the disc rotor and wheel hub by
one hole.

4.

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. Replace disc
rotor if thickness is under the wear limit.

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.
