Rear brake pads — check and replacement

Note: Dust generated by brake wear and deposited on brake components may contain asbestos. Do not blow it with compressed air or inhale it; it is dangerous for your health. Wipe off dust using a clean, dry cloth, working in a well-ventilated area, then discard the cloth. Although basic friction materials do not contain asbestos, please take precautions.

Don't save money when purchasing brake components. Brake pads should always be replaced to ensure uniform braking performance. For this reason, purchase components only from Nissan dealers.

1. Place the car on a level surface, apply the handbrake and select reverse gear first (manual transmission) or "R" (automatic transmission). Block the front wheels. Loosen the wheel nuts, jack up the rear of the car, and use stands for safety. Remove the wheel and release the handbrake completely.

2. Loosen the handbrake cable bolt on the caliper (photo) and disconnect the cable and pipe from the lever. Remove the clamp from the spring that secures the flexible hose to the shock absorber.




3. Move the caliper body outward so that the piston can be inserted into the cylinder.

4. Unscrew the rear caliper guide pin bolt, if necessary use a thin double-sided wrench. Rotate the caliper housing upward to remove the brake pads (photo). Do not press the brake pedal until the caliper is assembled.



5. Handle the pads attached to the metal base of each pad with care. Mark them so that they are reinstalled in their original position. Pay attention to the uniform wear of the brake pads.

6. First measure the thickness of the friction material remaining on each brake pad. If it is worn at any point to the minimum thickness or less, all four rear brake pads must be replaced. Also, the pads must be replaced if they are contaminated with lubricant, since it is almost impossible to properly degrease them.




7. If the pads are still serviceable, clean them using a clean, wire brush.

8. If there is uncertainty about the sliding ability of the caliper in the installation hanger, remove it, clean it, and lubricate the guide pins as described above. Check the brake disc.

9. When assembling, coat the anti-rattle springs with a thin layer of silicone grease - or RVS (Paly Butyl Cuprysil) based on high temperature lubricant for brake components. Do not allow lubricant to contaminate the friction material. Install the pads to the caliper mounting bracket so that the friction material is against the disc.

10. If new pads are being installed, the piston must be pulled into the cylinder to make room for the pads. Using long pliers and inserting them into the special cuts in the piston, screw the piston clockwise (looking at the piston from the side of the car) until it falls into place. When rotating, be careful not to damage the dust seal. Fill the master cylinder reservoir to the mark "Max".



11. Check the sliding of the caliper body in the installation suspension, then press the brake pedal several times until the pads move apart and come into contact with the brake disc at normal pedal pressure.




12. Connect the handbrake cable to the lever, and bolt it to the caliper body, ensuring the correct location of the pins. Install the wheel.

13. Repeat the entire procedure on the opposite brake caliper assembly, lower the vehicle to the ground and tighten the wheel nuts to the torque specified in the Specifications.

14. Check the fluid level in the reservoir.
