REAR DISC BRAKE
Revision: 2006 January2006 M35/M45
DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace if there are.
Runout Inspection
1. Fix disc rotor to wheel hub using wheel nuts (2 or more posi-
tions).
2. Inspect runout using dial gauge. [Measured at 10 mm (0.39 in)
inside disc edge.]
NOTE:
Before measuring, make sure that wheel bearing axial end play
is within the specification. Refer to RAX-5, "
WHEEL BEARING
INSPECTION" .
3. When runout exceeds limit value, displace mounting positions of
disc rotor by one hole. And then find a position of the minimum value for runout.
4. Replace disc rotor if it is outside repair limit after performing the above operation.
Thickness Inspection
Check the thickness of the disc rotor using a micrometer. Replace
disc rotor if the thickness is under the wear limit.
BRAKE BURNISHING PROCEDURE
Burnish contact surfaces between disc rotors and pads according to following procedure after refinishing or
replacing rotors, after replacing pads, or if a soft pedal occurs at very low mileage.
CAUTION:
Be careful of vehicle speed because the 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 the vehicle on a 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 for a few minutes to cool the brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted. Runout limit : 0.055 mm (0.0022 in)

PRECAUTIONS
Revision: 2006 January2006 M35/M45
Precautions for Brake ControlNFS000Q1
Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. This is normal condition.
When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid
level, and oil leaks.
If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
ABS might be out of order or malfunctions by putting a radio (wiring inclusive), an antenna and a lead-in
wire near the control unit.
If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
VDC system may not operate normally or a VDC OFF indicator lamp or SLIP indicator lamp may light.
–When replacing the following parts with parts other than genuine parts or making modifications: Suspen-
sion-related parts (shock absorber, spring, bushing, etc.), tires, wheels (other than specified sizes), brake-
related parts (pad, rotor, caliper, etc.), engine-related parts (muffler, ECM, etc.) and body reinforcement-
related parts (roll bar, tower bar, etc.).
–When driving with worn or deteriorated suspension, tires and brake-related parts.

Basic InspectionNFS000QK
BASIC INSPECTION 1: BRAKE FLUID LEVEL, LEAK INSPECTION AND BRAKE PAD
1. Check fluid level in brake reservoir tank. If fluid level is low, refill brake fluid. Refer to BR-10, "CHECKING
BRAKE FLUID LEVEL" .
2. Check for leakage in brake tubes or hoses and around ABS actuator and electric unit (control unit). If
there is leaking or seeping fluid, check the following items.
If the brake tube connections at ABS actuator and electric unit (control unit) are loose, tighten flare nuts
to the specified torque. Then inspect again and confirm that there is no leakage.
If flare nuts or screws of ABS actuator and electric unit (control unit) are damaged and loose, replace
damaged parts. Then inspect again and confirm that there is no leakage.
If there is leakage at any location other than ABS actuator and electric unit (control unit) connections,
wipe away leakage with clean cloth. Then inspect again and confirm that there is no leakage.
If there is leakage from ABS actuator and electric unit (control unit), wipe away leakage with clean cloth.
Then inspect again. If there is still leakage, replace ABS actuator and electric unit (control unit).
CAUTION:
ABS actuator and electric unit (control unit) cannot be disassembled.
3. Check brake disc rotor and pads. Refer to BR-28, "
DISC ROTOR INSPECTION" (front disc rotor), BR-23,
"PAD WEAR INSPECTION" (front brake pad), BR-34, "DISC ROTOR INSPECTION" (rear disc rotor), BR-
29, "PAD WEAR INSPECTION" (rear brake pad).
BASIC INSPECTION 2: LOOSENESS OF POWER SYSTEM TERMINALS AND BATTERY
Check battery for looseness on battery positive/negative terminals and ground connection. Also make sure
battery voltage does not drop and alternator is normal.
BASIC INSPECTION 3: ABS WARNING LAMP, BRAKE WARNING LAMP, VDC OFF INDICATOR
LAMP AND SLIP INDICATOR LAMP
ON and OFF Timing for Warning Lamp and Indicator Lamp
