Pad Replacement

WARNING: This page is about a different car, the 2005 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Clean brake pads with a vacuum dust collector to minimize the hazard of airborne particles or other materials.
CAUTION:
  • When cylinder body is open, do not depress brake pedal because piston will pop out.
  • Be careful not to damage piston boot or get oil on rotor. Always replace shims in replacing pads.
  • If shims are rusted or show peeling of rubber coat, replace them with new shims.
  • It is not necessary to remove connecting bolt except for disassembly or replacement of caliper assembly. In this case, suspend cylinder body with wire so as not to stretch brake hose.
  • Burnish the brake contact surfaces after refinishing or replacing drums or rotors, after replacing pads or linings, or if a soft pedal occurs at very low mileage.

    Refer to BRAKE BURNISHING PROCEDURE .

  1. Remove master cylinder reservoir cap.
  2. Remove wheel and tire. Refer to TIRE ROTATION .
  3. Remove brake cable mounting bolt and lock spring.

  4. Release parking brake control lever, then disconnect cable from the caliper.
  5. Remove upper pin bolt.
  6. Open cylinder body downward and secure with wire as shown in Fig 2. Then remove pad retainers, and inner and outer shims.
    • Standard pad thickness: 10 mm (0.39 in) 
    • Pad wear limit: 2.0 mm (0.079 in)

  7. When installing new pads, push piston into cylinder body by gently turning piston clockwise using suitable commercial service tool or long nose pliers, as shown in Fig 3 and Fig 4.
    NOTE: Carefully monitor brake fluid level because brake fluid will return to reservoir when pushing back piston.
