PRECAUTIONS
• Tighten the brake tube flare nut to the specified torque with a crow-
foot (A) and torque wrench (B).
• Always conform the specified tightening torque when installing the
brake pipes.
• Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction is
detected, replace part with a new one.
• Turn the ignition switch OFF and disconnect the ABS actuator and
electric unit (control unit) connector or the battery negative terminal
before performing the work.
Precaution for Brake Control
INFOID:0000000001635158
• 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.
• 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: 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.
