1) Remove mud and foreign matter from the caliper
body assembly and the support.

CAUTION:
Be careful not to allow foreign matter to enter
the brake hose connector.
2) Place a wooden block in the caliper body as
shown in the figure to prevent the piston from jump-
ing out and being damaged.
3) Gradually apply compressed air via the brake
hose installation hole to push the piston out.

4) Remove the piston boot.

5) Remove the piston seal from caliper body cylin-
der.

CAUTION:
Do not damage the cylinder and piston seal
groove.

6) Remove the guide pin and boot from caliper
body.

D: ASSEMBLY

1. 16-INCH TYPE

1) Clean the inside of the caliper body using brake
fluid.
2) Apply a coat of brake fluid to piston seal and in-
stall the piston seal to the caliper body groove.
3) Apply a coat of brake fluid to the inner surface of
cylinder and the entire outer surface of the piston.
4) Apply grease contained in the piston seal kit to
the boot, and install it to the groove at the end of the
cylinder.
5) Insert the piston into cylinder.

CAUTION:
Do not force the piston into cylinder.

6) Position the boot in the grooves on cylinder and
piston.

7) Apply grease contained in the piston seal kit to
the lock pin, guide pin outer surface, cylinder inner
surface, and boot grooves.

8) Insert the lock pin and guide pin boot into the
support.

CAUTION:
After inserting the lock pin and guide pin into
the specified locations, check by hand that the
pin moves and slides smoothly with no abnor-
malities when it reaches the end.

2. 17-INCH TYPE

Refer to 16-inch type. <Ref. to BR-18, 16-INCH

A: REMOVAL

1) Lift up the vehicle, and remove the rear wheels.
2) Remove the caliper bolt.

3) Raise the caliper body and support it.

NOTE:
Do not disconnect the brake hose from the caliper
body.
4) Remove the pads.

B: INSTALLATION

1) Apply a thin coat of Molykote M7439 (Part No.
K0777YA000) or grease contained in the pad kit to
the pad clip.

2) Apply a thin coat of Molykote AS880N (Part No.
K0779YA010) or grease contained in the pad kit to
the contact surface between the pad and shim.
3) Install the pad to support.
4) Install the caliper body to the support.

Tightening torque:

Solid disc brake model

27 N·m (2.8 kgf-m, 19.9 ft-lb)

Ventilated disc brake model

37 N·m (3.7 kgf-m, 27.2 ft-lb)

C: INSPECTION

Check the pad thickness A.

NOTE:
• Always replace the pads of both wheels and both
sides as a set.
• Replace pad clips if they are twisted or worn.
• A wear indicator is installed on the inner disc
brake pad. If the pad is worn to the limit, the end of
wear indicator contacts disc rotor, and a squeaking
sound is heard as the wheel rotates. If the sound is
heard, replace the pad.
• Replace the pad if there is oil or grease on it.
