NBR167
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.

Pad ReplacementNJBR0142WARNING:
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
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 ªBrake Burnishing Procedureº, ªON-VEHICLE
SERVICEº, BR-7.

RemovalNJBR0143WARNING:
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 enter-
ing the system.
CAUTION:
Care should be taken as not to let:
+Air enter the cylinder body and brake hose.
+Brake fluid spill from the cylinder body and brake hose.
DisassemblyNJBR0144Remove pin bolts and pins.
NOTE:
Cylinder body can not be disassembled.
InspectionNJBR0145CALIPERNJBR0145S01CAUTION:
Do not drain any brake fluid from cylinder body. Cylinder body
can not be disassembled.
Cylinder BodyNJBR0145S0101Check cylinder body for score, rust, wear, damage or presence of
foreign materials. If any of the above conditions are observed,
replace cylinder body.
Torque MemberNJBR0145S0102Check for wear, cracks or other damage. Replace if necessary.
Pin and Pin BootNJBR0145S0104Check for wear, cracks or other damage.
Replace if any of the above conditions are observed.

AdjustmentNJBR0047Before or after adjustment, pay attention to the following points.
+For rear disc brake be sure that toggle lever returns to stop-
per when parking brake lever is released.
+There is no drag when parking brake lever is released.
+Vehicle is unladen.
1. Adjust clearance between shoe and drum or pad and rotor as
follows:
a. Release parking brake lever and loosen adjusting nut.
b. Depress brake pedal fully at least 10 times with engine run-
ning.
SBR756E
2. Pull control lever 10 times or more to make a (full) lever stroke
of 195 mm (7.68 in). At 4 to 6 notches, adjust the parking brake
cable by turning the adjusting nut.
SBR033A
3. Pull control lever with specified amount of force. Check lever
stroke and ensure smooth operation.
Number of notches

4. Bend warning lamp switch plate to ensure:
+Warning lamp comes on when lever is lifted ªAº notches.
+Warning lamp goes out when lever is fully released.

PurposeNJBR0082The ABS consists of electronic and hydraulic components. It allows for control of braking force so that lock-
ing of the wheels can be avoided.
The ABS:
1) Ensures proper tracking performance through steering wheel operation.
2) Enables obstacles to be avoided through steering wheel operation.
3) Ensures vehicle stability by preventing flat spins.
ABS (Anti-Lock Brake System) OperationNJBR0083+When the vehicle speed is less than 10 km/h (6 MPH) this system does not work.
+The Anti-Lock Brake System (ABS) has self-test capabilities. The system turns on the ABS warning lamp
for 1 second after turning the ignition switch ON. The system performs another test the first time the vehicle
reaches 6 km/h (4 MPH). A mechanical noise may be heard as the ABS performs a self-test. This is a
normal part of the self-test feature. If a malfunction is found during this check, the ABS warning lamp will
come on.
+During ABS operation, a mechanical noise may be heard. This is a normal condition.

System DescriptionNJBR0087SENSORNJBR0087S01The sensor unit consists of a gear-shaped sensor rotor and a sen-
sor element. The element contains a bar magnet around which a
coil is wound. The sensor is installed on the back side of the brake
rotor. Sine-wave current is generated by the sensor as the wheel
rotates. The frequency and voltage increase(s) as the rotating
speed increases.
SBR759E
CONTROL UNITNJBR0087S02The control unit computes the wheel rotating speed by the signal
current sent from the sensor. Then it supplies a DC current to the
actuator solenoid valve. It also controls ON-OFF operation of the
valve relay and motor relay. If any electrical malfunction should be
detected in the system, the control unit causes the warning lamp
to light up. In this condition, the ABS will be deactivated by the
control unit, and the vehicle's brake system reverts to normal
operation.

ABS ACTUATOR AND ELECTRIC UNITNJBR0087S03The ABS actuator and electric unit contains:
