1. Prepare the vehicle. Park the truck on a level surface, apply the parking brake, and chock the front wheels. Engage the parking brake.
2. Remove the wheels. Loosen the lug nuts slightly while the wheels are still on the ground, then use the jack and jack stands to raise the truck and remove the lug nuts. Pull the wheels off and set aside.
3. Remove the brake caliper. Remove the two bolts holding the caliper, then lift it off the rotor. Hang it securely out of the way with wire or a bungee cord.
4. Remove the brake pads. The brake pads are held in place by a clip. Remove the clip, then slide the pads out of the caliper bracket.
5. Inspect the rotor. Check the rotor for any signs of wear or damage, such as grooves, cracks, or pitting. If the rotor is damaged, it will need to be replaced.
6. Clean the caliper and bracket. Use a wire brush and brake cleaner to clean any dirt, rust, or debris from the caliper and bracket.
7. Install new brake pads. Place the new brake pads into the caliper bracket. Make sure that the pads are seated correctly and that the wear indicators are facing outward.
8. Install the brake caliper. Put the caliper back over the rotor and install the two bolts. Tighten the bolts until snug.
9. Bleed the brakes. This is necessary to remove any air from the brake lines. Start by opening the bleeder valve on one of the rear wheels. Have an assistant pump the brake pedal several times, then close the bleeder valve. Repeat this process until no more air bubbles come out of the bleeder valve.
10. Test the brakes. Take the truck for a test drive to make sure that the brakes are working properly. Check the pedal feel, as well as the stopping distance.
11. Reinstall the wheels. Put the wheels back on and tighten the lug nuts. Lower the truck and remove the jack stands.
12. Test drive the vehicle. Take the truck for a short test drive to make sure the brakes are working properly.
It's important to follow these steps carefully to ensure that the rear brakes are replaced correctly and that the vehicle is safe to drive. If you're at all unsure of your abilities to replace the brakes yourself, it's best to take your vehicle to a qualified mechanic.
