WARNING:
●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 when replacing
pads.
●If shims are rusted or show peeling of the 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 BR-10, "
Brake Burnishing
Procedure" .
InspectionEFS000CH
PAD THICKNESS
Check pad thickness by lifting vehicle, removing the wheel, and
looking through check hole on cylinder body. If necessary, use a
scale.

Pad Replacement
EFS000CI
REMOVAL
CAUTION:
When replacing brake pads, always replace inner shims, outer shims, and shim covers as a set.
1. Remove master cylinder reservoir tank cap.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire, and remove pads, pad retainers,
shims and pad return springs.
INSTALLATION
1. Apply brake grease on back of the pad and both sides of the shim. Install inner shim and inner shim cover
to inner pad, outer shim to outer pad.
2. Apply brake grease on the pad retainer pad contact surface. Install pad retainers, pads and pad return
springs to the torque member.
3. Connect cylinder body to the torque member.
CAUTION:
When replacing pads with new ones, press piston in until the pads can be installed. Carefully mon-
itor brake master cylinder reservoir fluid level. Brake fluid will return, raising master cylinder res-
ervoir tank fluid level.
4. Insert lower sliding pin bolt and tighten to the specified torque.
5. Check brakes for drag.
Caliper Removal and InstallationEFS000CJ
REMOVAL
1. Connect a vinyl tube to the air bleeder.
2. Drain brake fluid gradually from air bleeder while depressing brake pedal.
3. Remove union bolts and torque member mounting bolts, and

Precautions for brake systemEFS001B6
●Recommended fluid is brake fluid “DOT 3 ”or “DOT 4”.
●Never reuse drained brake fluid.
●Be careful not to splash brake fluid on painted areas.
●To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.
●Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
●Use flare nut wrench when removing and installing brake tube.
●Always torque brake lines when installing.
●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 BR-10, "
Brake Burnishing
Procedure" .
●Before working, turn OFF ignition switch. Disconnect connectors
for ABS actuator and control module or battery terminals.
WARNING:
●Clean brake pads and shoes with a waste cloth, then wipe
with a dust collector.
Precautions for brake controlEFS001B7
●If malfunction is indicated by 4WD warning lamp and/or ABS warning lamp, collect necessary information
from customer (what symptoms are present under what conditions). Find out possible causes before start-
ing service. Besides electrical system inspection, check operation of ABS actuator.
●If malfunction is detected, proceed to trouble diagnosis after checking tire pressure and tire wear.
●Stopping distance or steering stability may be deteriorated by the following conditions. Tire size and type
are in improper combination. Brake pads are not Nissan genuine parts.
●Fitting tires of different size on vehicle can be cause of longitudinal vibration. Always use tires of the same
size and brand. Exchange front and rear tires on the following conditions: Longitudinal vibration occurs in
vehicle with tires of the same size and brand. After replacement, perform trouble diagnosis. 1580|None
●4WD/ABS function may have a failure or error under following condition: There is radio, antenna, or
antenna lead-in wire (including wiring) near control module.
●If aftermarket parts (e.g. Car stereo equipment, CD player) have been installed, check electrical har-
nesses for pinches, open, and improper wiring.
