Did this today. 1 hour including removing mud!! Do one side at a time.
Rear Brake Pad Replacement (Front is similar):
1. Jack up support the truck on the frame with jack stands.
2. Remove wheel & Tire (torque lug nuts to 103 ft lb on reinstall)
3. Clean all mud/dirt with low pressure water hose and soft brush. Be careful of wear sensor on right side. (Left side on front brakes)
This is the sensor.
4. Tools you need:
13mm 6pt socket and ratchet
Torque Wrench
8" C Clamp
Small Block of wood or old pad
Needle Nose Pliers ( You MAY need these to GENTLY coax the wear sensor out)
15mm Open End Wrench
Common Screwdriver, 6" (for easing out the pads)
Bungee Cord (for supporting the Caliper out of the way)
5. CAREFULLY remove the wear sensor by pulling it straight back and out. It is held in by a spring clip.
The clip is in the top of the inside pad in the caliper, look close!
6. Remove the bleeder screw cover and remove the clip holding the wear sensor cable. Carefully move the sensor and cable out of the way.
7. Remove the brake caliper lower bolt. You will use the 15mm wrench to hold the slide and the 13mm to remove the bolt.
8. Rotate the caliper upward and support it with the bungee cord. These pads a 4mm thick or about .130". The limit is .12" or 3 mm. If the wear sensor is activated, you need to install a new sensor. (These were Federo pads with only 9000 miles on them!)
9. Remove the outer pad by sliding it out of the clips. Install the new pad into the clips. NOTE: If your pads a chamfered on only one edge, the chamfer will go to the leading edge or toward the rotation while moving forward.
10. Remove the inner pad carefully. RETAIN the wear sensor spring clip!! Install the spring clip in the new pad and slip the new pad into the clips. Notice the spring clip installs in the narrow ridge that fits into the groove in the wear sensor.
11. Using the C Clamp and block of wood or old pad, compress the piston back into the caliper. Do not compress it too far and pinch the seal around the piston. Remove the C Clamp.
12. Remove the bungee cord and rotate the caliper down and over the new pads. You may have to move it outward on the slides to clear the outside pad.
13. Install the lower caliper bolt. Hold the inner nut with the wrench and torque the bolt to 26 ft lbs.
14. Reattach the wear sensor cable support to the bleeder screw. Reinstall the bleeder screw cap.
15. Carefully reinstall the wear sensor into the inner pad clip.
16. Reinstall wheel and torque lug nuts to 103 ft lbs.
Use the same procedure for the left side. There is no wear sensor on the left side.
Start the truck and depress the brakes a few times to seat the caliper piston against the pads.
You are done!!
