●
It is not necessary to remove connecting bolt except for
disassembly or replacement of caliper assembly. In this
case, suspend cylinder body with wire so as not to
stretch brake hose.
●
Burnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage.
Refer to “Brake Burnishing Procedure”, “CHECK AND
ADJUSTMENT”, BR-7.
1. Remove master cylinder reservoir cap.
2. Remove brake cable mounting bolt and lock spring.
3. Release parking brake control lever, then disconnect cable
from the caliper.
4. Remove upper pin bolt.
5. Open cylinder body downward. Then remove pads inner and
outer shims.
Standard pad thickness:
9.3 mm (0.366 in)
Pad wear limit:
2.0 mm (0.079 in)
6. When installing new pads, push piston into cylinder body by
gently turning piston clockwise, as shown.
Carefully monitor brake fluid level because brake fluid
will return to reservoir when pushing back piston.
7. Adjust the piston to the right angle as shown in the figure.

Cylinder Body
●
Check inside surface of cylinder for score, rust, wear, dam-
age 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 elimi-
nated by polishing surface with a fine emery paper.
Replace cylinder body if necessary.
Torque Member

CAUTION:
Piston sliding surface is plated. Do not polish with emery
paper even if rust or foreign matter is stuck to sliding sur-
face.
