2003 GMC Safari Brake Disc Parts Questions & Experts Answers

• Q: How to replace the rear brake disc on 2003 GMC Safari?

  A: Vehicle elevation for support becomes necessary before starting the replacement process for the rear brake rotor. Mark the relationship between rotor and hub before removing the tire wheel combination. Hook a brake caliper support to the caliper to stop hydraulic damage through the hose while you remove its bracket mounting bolts. Remove the brake caliper assembly with the bracket while leaving the hydraulic hose connected and then unscrew the rotor retaining push nuts from wheel studs if such nuts exist. A deadblow hammer strike on the rotor end followed by turning motion and pulling direction away from the axle separates the hub from the rotor for removal. The installation process requires users to clean rust and foreign matter from the surface of rotor and flange by utilizing wheel hub resurfacing kit (J 42450-A) alongside rotor resurfacing kit (J 41013). First turn and gently push the rotor to the axle direction before reattaching the caliper and bracket assembly. You must remove the supply adhesive label before following these steps: wash the threads with brake parts cleaner and secure them by applying threadlocker gm p/n 12345493 (Canadian P/N 10953488) to the threads. Reinstall the tire and wheel assembly then lower the vehicle. Next apply the brake pedal slowly to two-thirds of pedal extend then release it gradually. Repeat this procedure until pedestrian resistance becomes strong. Complete the fluid level in the master cylinder reservoir with fresh brake fluid according to specifications.
