lapsible spacer to the drive pinion.
CAUTION:
●Be careful of the mounting orientation of the collapsible
spacer.
●Do not reuse the collapsible spacer.

Checking Brake Fluid Level EFS000C5
●Confirm reservoir tank fluid level is within specifications
(between MAX and MIN lines).
●Visually check around reservoir tank for fluid leaks.
●If fluid level is excessively low, check brake system for leaks.
●If warning lamp remains illuminated after parking lever is
released, check brake system for fluid leakage.
Checking Brake LineEFS001C5
CAUTION:
If leakage occurs around joints, retighten or, if necessary, replace damaged parts.
1. Check brake line (tube and hoses) for cracks, deterioration or
other damage. Replace and damaged parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
Changing Brake FluidEFS000C3
CAUTION:
●Refill with new brake fluid “DOT 3 or DOT 4”.
●Always keep fluid level higher than minimum line on reservoir tank.
●Never reuse drained brake fluid.
●Be careful not to splash brake fluid on spill or splash on painted areas; it may cause paint damage.
If brake fluid is splashed on painted areas, wash it away water immediately.
1. Connect a vinyl tube to the air bleeder.
2. Drain brake fluid gradually from the air bleeder of each wheel
while depressing the brake pedal.
3. Turn OFF ignition switch. Remove ABS actuator connector.

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.
