Using a micrometer, check thickness of disc rotor. If thickness is out-
side the specifications, replace disc rotor.
ASSEMBLY
CAUTION:
When assembling, use only specified lubricant.
1. Apply rubber grease to new piston seal and install on cylinder body.
2. Apply rubber grease (CL25VF) or polyglycol ether based lubri- cant (AD22VK) to piston boot and apply brake fluid to piston.
Cover the piston end with piston boot, and install cylinder-side
lip on piston boot properly into groove on cylinder body.
3. Press piston into cylinder body by hand to assemble piston-side lip on piston boot properly into a groove on piston.
CAUTION:
Press piston evenly and change pressing point to prevent
inner wall of cylinder from being rubbed.
4. Install sliding pins and sliding pin boots to the torque member.
5. Install pads, shims, pad return spring (AD22VK) and pad retainers on the torque member. Refer to BR-26,
"Removal and Installation of Brake Pad".
6. Install cylinder body to torque member.
7. Tighten sliding pin bolts to specified torque. Refer to BR-25, "
Component".
8. Install the caliper assembly. Refer to BR-30, "

Brake Burnishing Procedure
INFOID:0000000005397002
Burnish the new braking surfaces according to following procedure after refinishing or replacing disc rotors,
pads, or if a soft pedal occurs at very low mileage.
CAUTION:
• Be careful of vehicle speed because brake does not operate easily until pad and disc rotor are securely fitted.
• Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake pedal for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.

PRECAUTIONS
5. When the repair work is completed, return the ignition switch to the
″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of a ll control units using CONSULT-III.
Precaution for Brake SystemINFOID:0000000005397021
CAUTION:
• Refer to MA-14
for recommended brake fluid.
• Never reuse drained brake fluid.
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
• To clean or wash all parts of master cylin der and disc brake caliper, use clean brake fluid.
• Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic sys-
tem.
• Use flare nut wrench when removing and installing brake
tube.
• If a brake fluid leak is found, the part must be disassembled without fail. Then it has to be replaced with a new one if a
defect exists.
• Turn the ignition switch OFF an d remove the connector of the
ABS actuator and electric unit (c ontrol unit) or the battery ter-
minal before performing the work.
• Always torque brake lines when installing.
• Burnish the brake contact surf aces after refinishing or replac-
ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage. Refer to BR-34, "
Brake Burnishing Proce-
dure".
WARNING:
• Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
Precaution for Brake ControlINFOID:0000000005397022
• During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
• Just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard from engine compartment. This is normal due to the self check operation.
• Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.
• When an error is indicated by ABS or another warning la mp, collect all necessary information from customer
(what symptoms are present under what conditions) and check for simple causes before starting diagnosis.
Besides electrical system inspection, check brake booster operation, brake fluid level, and fluid leaks.
• If incorrect tire sizes or types are installed on the v ehicle or brake pads are not Genuine NISSAN parts, stop-
ping distance or steering stability may deteriorate.
• If there is a radio, antenna or related wiring near t he control module, ABS function may have a malfunction
or error.
• If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits or improper wiring.
Precaution for CAN SystemINFOID:0000000005397023
• Do not apply voltage of 7.0V or higher to terminal to be measured.
• Maximum open terminal voltage of test er in use must be less than 7.0V.
• Before checking harnesses, turn ignition sw itch OFF and disconnect battery negative cable.

• If ABS actuator and electric unit (control unit) connec tion is loose, tighten the piping to the specified
torque and recheck for leaks.
• If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) threads,
replace the damaged part and recheck for leaks.
• When there is fluid leaking or seeping from a fluid connection, use a clean cloth to wipe off the fluid and recheck for leaks. If fluid is still seeping out, replace the damaged part. If the fluid is leaking at the ABS
actuator and electric unit (control unit), replace the ABS actuator and electric unit (control unit) assem-
bly.
CAUTION:
The ABS actuator and electric unit (control unit) cannot be disassembl\
ed and must be replaced
as an assembly.
3. Check the brake pads for excessive wear.
POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure the battery positive cable, negative cabl e and ground connection are not loose. In addition, make
sure the battery is sufficiently charged.
ABS WARNING LAMP INSPECTION
1. Make sure ABS warning lamp turns on for approximately 2 seconds when the ignition switch is turned ON. If it does not, check CAN communications. If ther e are no errors with the CAN communication system,
replace the combination meter. Refer to IP-12, "
Removal and Installation".
2. Make sure the lamp turns off approximately 2 seconds after the ignition switch is turned ON. If the lamp does not turn off, conduct self-diagnosis of ABS actuator and electric unit (control unit). If no malfunctions
are detected in self-diagnosis, replace combination meter. Refer to IP-12, "
Removal and Installation".
3. After conducting the self-diagnosis, be sure to erase the error memory. Refer to BRC-20, "
CONSULT-III
Function (ABS)".
