Clean brake pads with a vacuum dust collector to minimize
the hazard of airborne particles or other materials.
CAUTION:
lWhen cylinder body is open, do not depress brake pedal
because piston will pop out.
lBe careful not to damage piston boot or get oil on rotor.
Always replace shims in replacing pads.
lIf shims are rusted or show peeling of rubber coat,
replace them with new shims.

lIt 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.
lBurnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage.
Refer to ªBrake Burnishing Procedureº, ªCHECK AND
ADJUSTMENTº, 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.

8. As shown in the figure, align the piston's concave to the
pad's convex, then install the cylinder body to the torque
member.
9. Install brake cable, brake cable mounting bolt, lock spring
and master cylinder reservoir cap.
Removal
WARNING:
Clean brake pads with a vacuum dust collector to minimize
the hazard of airborne particles or other materials.
1. Remove brake cable mounting bolt and lock spring.
2. Release parking brake control lever, then disconnect cable
from the caliper.
3. Remove torque member fixing bolts and connecting bolt.
It is not necessary to remove connecting bolt except for
disassembly or replacement of caliper assembly. In this
case, suspend caliper assembly with wire so as not to
stretch brake hose.
Disassembly
1. Remove piston by turning it counterclockwise with long nose
pliers or suitable tool.
2. Pry off snap ring A from piston with suitable pliers and
remove adjusting nut.

WARNING:
Clean brake pads with a vacuum dust collector to minimize
the hazard of airborne particles or other materials.
1. Remove brake cable lock spring.
2. Release parking brake control lever, then disconnect cable
from the caliper.
3. Remove torque member fixing bolts and connecting bolt.
4. Remove brake hose connecting bolt.
5. Plug off the brake hose and cylinder body to prevent air
entering the system.

lBrake fluid spill from the cylinder body and brake hose.
Disassembly
Remove pin bolts and pins.
NOTE:
Cylinder body can not be disassembled.
Inspection
CALIPER
CAUTION:
Do not drain any brake fluid from cylinder body. Cylinder
body can not be disassembled.
Cylinder Body
Check cylinder body for score, rust, wear, damage or presence
of foreign materials. If any of the above conditions are observed,
replace cylinder body.
Torque Member
Check for wear, cracks or other damage. Replace if necessary.
Pin and Pin Boot
Check for wear, cracks or other damage.
Replace if any of the above conditions are observed.

Wheel Cylinder Overhaul
lCheck all internal parts for wear, rust and damage. Replace
if necessary.
lPay attention so as not to scratch cylinder when installing
pistons.
Inspection Ð Drum
Maximum inner diameter:
204.5 mm (8.05 in)
Maximum out-of-round:
0.03 mm (0.0012 in)
lContact surface should be fine finished with No. 120 to 150
emery paper.
lUsing a drum lathe, resurface brake drum if it shows scoring,
partial wear or stepped wear.
lAfter brake drum has been completely reconditioned or
replaced, check drum and shoes for proper contact pattern.
Inspection Ð Lining
Check lining thickness.
Standard lining thickness:
4.5 mm (0.177 in)
Lining wear limit:
1.5 mm (0.059 in)
Installation
lAlways perform shoe clearance adjustment. Refer to
BR-49.
lBurnish the brake contact surfaces after refinishing or
replacing drums or rotors, after replacing pads or
linings, or if a soft pedal occurs at very low mileage.
Refer to ªBrake Burnishing Procedureº, ªON-VEHICLE
SERVICEº, BR-7.
1. Fit toggle lever to brake shoe with retainer ring.
2. Apply brake grease to the contact areas shown at left.
