WA RN ING:
lClean 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 when replacing
pads.
lIf shims are rusted or show peeling of the 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 drums or rotors, after replacing
pads or linings, or if a soft pedal occurs at very low mileage. Refer toBR-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.

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.

Precautions for brake systemEFS001B6
lRecommended fluid is brake fluid “DOT 3 ”or “DOT 4”.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas.
lTo clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.
lNever use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
lUse flare nut wrench when removing and installing brake tube.
lAlways torque brake lines when installing.
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 toBR-10, "
Brake Burnishing
Procedure".
lBefore working, turn OFF ignition switch. Disconnect connectors
for ABS actuator and control module or battery terminals.
WAR NIN G:
lClean brake pads and shoes with a waste cloth, then wipe
with a dust collector.
Precautions for brake controlEFS001B7
lIf 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.
lIf malfunction is detected, proceed to trouble diagnosis after checking tire pressure and tire wear.
lStopping 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.
lFitting 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
l4WD/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.
lIf aftermarket parts (e.g. Car stereo equipment, CD player) have been installed, check electrical har-
nesses for pinches, open, and improper wiring.

PERIODIC MAINTENANCE
NOTE:
lMaintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”.
l(1) If valve noise increases, check valve clearance.
l(2) Never use CG-4 oil.
l(3) Oil filter element assembly and O-ring seal are replacement parts.
l(4) First replace at 100,000 Km (60,000 miles), then every 60,000Km (36,000 miles). After first replacement, perform "I"
(checking the mixture ratio and correcting the mixture ratio if necessary) at the middle of replacement interval.
l(5) If engine power decreases, black exhaust smoke is emitted or engine noise increases, perform this maintenance item.
