2.

Apply rubber grease to piston boot. Cover the piston end with
the piston boot, and install cylinder-slide lip on piston boot prop-
erly into the groove on cylinder body.

CAUTION:

Do not reuse the piston boot.

3.

Apply brake fluid to the piston, and press piston into cylinder
body by hand to assemble piston-side lip on piston boot properly
into a groove on piston.

CAUTION:

Press piston evenly and change pressing point to prevent
inner wall of cylinder from being rubbed.

4.

Fix piston boot with retaining ring.

CAUTION:

●

Make sure the boot is firmly in the cylinder body groove.

●

Do not reuse the retaining ring.

5.

Install the sliding pin bolt and sliding pin boot to the torque member.

6.

Apply PBC (Poly Butyl Cuprysil) grease or silicone- based grease to the rear of the pad and to both sides
of the shim, and attach the inner shim and shim cover to the inner pad, and the outer shim to the outer
pad.

7.

Install the pad retainer and pad to the torque member.

CAUTION:

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.

8.

After assembling shims and shim cover to pad, install it to the
torque member.

9.

Install cylinder body. Tighten sliding pin bolts to the specified
torque. Refer to 

BR-27, "Components"

 .

REAR DISC BRAKE

DISC ROTOR INSPECTION
Visual Inspection

Check surface of the disc rotor for uneven wear, cracks, and serious damage. If a malfunction detected,
replace applicable part.

Runout Inspection

1.

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

2.

Inspect runout using a dial gauge. 

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

RAX-6, "WHEEL

BEARING INSPECTION"

 .

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.

Thickness Inspection

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

Brake Burnishing Procedure

NFS000TD

Burnish the brake pad and disc rotor mutually contacting surfaces of disc rotor according to following proce-
dure 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 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 brake.

4.

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

Measurement position:

At a point 10.0 mm (0.394 in) from outer edge of 
disc rotor
