HINT:
At the time of installation, please refer to the following item.
Install the flexible hose lock securely in the lock hole in the cali-
per.
(b) Use a container to catch the brake fluid as it drains out.

REPLACEMENT
1. REMOVE REAR WHEEL
Remove the wheel and temporarily fasten the disc with the hub
nuts.
2. INSPECT PAD LINING THICKNESS
Check the pad thickness and replace pads if they are not within
specification.
Minimum thickness: 1.0 mm (0.039 in.)
3. REMOVE THESE PARTS
(a) Clip and 2 pins
(b) Anti-rattle spring
(c) 2 pads
(d) 4 anti-squeal shims
NOTICE:
The anti-rattle springs and clip can be used again provided
that they have sufficient rebound, no deformation, cracks
or wear, and have had all rust, dirt and foreign particles
cleaned off.
4. CHECK DISC THICKNESS AND RUNOUT
(See page BR-57)
5. INSTALL NEW PADS
NOTICE:
When replacing worn pads, the anti-squeal shims must be
replaced together with the pads.
(a) Draw out a small amount of brake fluid from the reservoir.
(b) Press in the pistons with a hammer handle or equivalent.
HINT:
Always change the pads on one wheel at a time as there
is a possibility of the opposite piston flying out.
If the piston is difficult to push in, loosen the bleeder plug
and push in the piston while letting some brake fluid es-
cape.

HANDLING PRECAUTIONS
1. The repair procedure for plastic body parts must conform with the type of plastic material.
2. Plastic body parts are identified by the codes in the following chart.
3. When repairing metal body parts adjoining plastic body parts (by brazing, frame cutting, welding,
painting etc.), consideration must given to the property of the plastic.
* Temperatures higher than those listed here may result in material deformation during repair.
