Pad ReplacementNJBR0037WARNING:
Clean brake pads with a vacuum dust collector to minimize the
hazard of airborne particles or other materials.
CAUTION:
+When cylinder body is open, do not depress brake pedal
because piston will pop out.
+Be careful not to damage piston boot or get oil on rotor.
Always replace shims in replacing pads.
+If shims are rusted or show peeling of rubber coat, replace
them with new shims.

+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 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-8.

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 pad retainers,
and inner and outer shims.
Standard pad thickness:

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.

RemovalNJBR0039WARNING:
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 dis-
assembly or replacement of caliper assembly. In this case,
suspend caliper assembly with wire so as not to stretch brake
hose.

InspectionNJBR0041CALIPERNJBR0041S01CAUTION:
Use brake fluid to clean cylinder. Never use mineral oil.
Cylinder BodyNJBR0041S0101+Check inside surface of cylinder for score, rust, wear, damage
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 eliminated
by polishing surface with a fine emery paper.
Replace cylinder body if necessary.
Torque MemberNJBR0041S0102Check for wear, cracks or other damage. Replace if necessary.
PistonNJBR0041S0103CAUTION:
Piston sliding surface is plated. Do not polish with emery
paper even if rust or foreign matter is stuck to sliding surface.
Check piston for score, rust, wear, damage or presence of foreign
materials.
Replace if any of the above conditions are observed.

ROTORNJBR0041S02Rubbing SurfaceNJBR0041S0201Check rotor for roughness, cracks or chips.
RunoutNJBR0041S02021. Secure rotor to wheel hub with two nuts (M12 x 1.25).
2. Check runout using a dial indicator.
Make sure that axial end play is within the specifications
before measuring. Refer to AX section (ªREAR WHEEL
BEARINGº, ªOn-vehicle Serviceº).
3. Change relative positions of rotor and wheel hub so that runout
is minimized.
Maximum runout:
0.07 mm (0.0028 in)
ThicknessNJBR0041S0203Rotor repair limit:
Standard thickness
10 mm (0.39 in)
