đź”§ F-150 - Rear Brake and Rotor Replacement
The rear brake pads and rotors need to be replaced together when the rotors are worn, scored, or below spec. On your F-150, this is a straightforward brake job, but you must compress the rear caliper piston fully before installing the new pads and rotor.

🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Remove the rear wheels

- Use the 13mm socket to remove the caliper bracket bolts.
- Remove the bracket from the axle flange.
Step 4: Remove the rotor
- Pull the rotor straight off the hub.
- If it is stuck, use a rubber mallet to tap around the rotor hat.
- If needed, use a flat-blade screwdriver to back off the parking brake shoes slightly through the access slot if the rotor will not clear.
Step 5: Prepare the hub and install the new rotor
- Use a wire brush and brake cleaner to clean rust from the hub face.
- Install the new rotor onto the hub.
- Make sure it sits flush with no rust trapped behind it.
Step 6: Install the caliper bracket and pads
- Reinstall the caliper bracket using the 13mm socket.
- Torque to 100 Nm (74 ft-lbs).
- Apply a thin coat of brake caliper slide pin grease to the slide pins if they were removed.
- Install the new pad hardware and pads into the bracket.
- Clean metal-to-metal contact points only.
Step 7: Compress the caliper piston and reinstall the caliper
- Use a C-clamp or brake caliper compression tool to push the piston fully back into the caliper.
- Slide the caliper over the new pads and bracket.
- Install the slide bolts with the 7mm socket.
- Torque to 35 Nm (26 ft-lbs).
Step 8: Reinstall the wheels
- Install both rear wheels by hand first.

âś… After Repair
