Pad Replacement

WARNING: This page is about a different car, the 2006 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.
