REMOVAL
CAUTION:
Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it
off immediately and wash with water if it gets on a painted surface.
1. Drain brake fluid. Refer to BR-9, "
Draining".
2. Remove air duct and air cleaner case. Refer to EM-26, "
Exploded View".
3. Separate the brake fluid level switch harness connector and harness clip.
4. Separate the brake tubes from the master cylinder assembly with a flare nut wrench.
CAUTION:
Never scratch the flare nut and the brake tube.
5. Remove the master cylinder assembly.
CAUTION:
 Depress the brake pedal several times to release the vacuum pressure from the brake booster.
Then remove the master cylinder assembly.
 Never depress the brake pedal after the master cylinder assembly is removed.
 The piston of the master cylinder assembly is exposed. Never damage it when removing the
master cylinder.

4. Apply brake fluid to piston (1). Push piston into cylinder body by
hand and push piston boot (2) piston-side lip into the piston
groove.
CAUTION:
Press the piston evenly and vary the pressing point to pre-
vent cylinder inner wall from being rubbed.
5. Apply rubber grease to bushing, install bushing to sliding pin.

BRAKE CALIPER ASSEMBLY : InspectionINFOID:0000000003811210
INSPECTION AFTER DISASSEMBLY
Cylinder Body
Check the inner wall of the cylinder for rust, wear, cracks or damage. Replace if necessary.
CAUTION:
Always clean with new brake fluid. Never clean with mineral oil such as gasoline and light oil.
Torque Member
Check the torque member for rust, wear, cracks or damage. Replace if necessary.
Piston
Check the surface of the piston for rust, wear, cracks or damage. Replace if necessary.
CAUTION:
A piston sliding surface is plated. Never polish with sandpaper.
Sliding Pin, Sliding Pin Boot and Bushing
Check the sliding pins, sliding boot and bushing for rust, wear, cracks or damage. Replace if necessary.
INSPECTION AFTER INSTALLATION
1. Check a drag of front disc brake. If any drag is found, follow the procedure described below.
2. Remove brake pads.
3. Press the piston.
CAUTION:
 Never damage the piston boot.
 When replacing a pad with new one, check a brake fluid level in the reservoir tank because brake
fluid returns to master cylinder reservoir tank when pressing piston in.
NOTE:
Use a disc brake piston tool to easily press piston.
4. Install brake pads.
5. Depress the brake pedal several times.
6. Check a drag of front disc brake again. If any drag is found, disassemble the cylinder body. Refer to BR-
36, "BRAKE CALIPER ASSEMBLY : Disassembly and Assembly".
7. Burnish contact surfaces after refinishing or replacing disc rotors, or if a soft pedal occurs at very low mile-
age. Refer to BR-13, "
DISC ROTOR : Inspection and Adjustment".

hand and push piston boot (2) piston side lip into the piston
groove.
CAUTION:
Press the piston evenly and vary the pressing point to pre-
vent cylinder inner wall from being rubbed.
5. Apply rubber grease to bushing, install bushing to sliding pin
bolt.
6. Apply rubber grease to the sliding pin bolts and the sliding pin
boots, install sliding pin boot to torque member.
7. Install the cylinder body to the torque member and tighten the
sliding pin bolts to the specified torque.

PRECAUTIONS
Precaution for Brake Control
INFOID:0000000003766861
 When starting engine or when starting vehicle just after starting engine, 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 customer
(what symptoms are present under what conditions) and check for estimate causes before starting diagnos-
tic 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.
Precautions for Harness RepairINFOID:0000000003859437
COMMUNICATION LINE
 Solder the repaired area and wrap tape around the soldered area.
NOTE:
A fray of twisted lines must be within 110 mm (4.33 in).
 Bypass connection is never allowed at the repaired area.
NOTE:
Bypass connection may cause communication error as spliced
wires that are separate from the main line or twisted lines lose
noise immunity.
 Replace the applicable harness as an assembly if error is detected
on the shield lines of communication line.

- When replacing the following parts with parts other than genuine parts or making modifications: Suspension
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.
