  Q: How to replace the rear brake pads on GMC C2500?

  A: Before working on brake pads you should extract 2/3 of the brake fluid from the master cylinder. Lift the car to work on it and take off the tire while pulling out the wheel components. A safe check of caliper movement comes first before you lift the caliper and use thick wire to hang it from the frame without resting on the brake hose. To proceed first take off the backing plate bolts for 15/25 series and then eliminate brake pads from caliper brackets of both series, disposing of clips found inside. Check the caliper and mounting bracket first and then place the clips inside the caliper mounting bracket hollow area while fitting brake pads onto it both for 15 series and 25 series applications. Keep the number of wear indicators correct for inner and outer pads. Put the caliper mounting bracket on the backing plate assembly of (15 series) and (25 series). Apply threadlocker gm p/n 12345493 or red loctite (TM) #272 to the bolt threads after cleaning the brake parts cleaner from the bolt threads and removing any remaining old adhesive. Secure the caliper mounting bracket bolts into the Steering Knuckle by tightening them to 200 n.m (148 lb ft) for (15 series) and 165 n.m (122 lb ft) for (25 series). Reinstall the caliper after putting back the wheel assembly then take off protection stands to lower the car. Place new brake fluid into the master cylinder then press the brake pedal at a slow and strong pace to let brake pads find their position while also performing brake burnishing when required.
