Tools You'll Need:
* Jack and jack stands (safety first! Never work under a vehicle supported only by a jack)
* Wheel chocks
* Lug wrench
* Socket wrench set (metric)
* Torque wrench
* Caliper piston compression tool (C-clamp can work in a pinch, but a proper tool is recommended)
* Rotor removal tool (optional, but helpful if the rotor is stuck)
* Wire brush or brake cleaner
* Gloves
* Safety glasses
Procedure:
1. Safety First: Park your F-150 on a level surface, engage the parking brake, and chock the rear wheels. Raise the front of the truck using the jack and securely place it on jack stands.
2. Remove the Wheel: Remove the lug nuts using the lug wrench. Keep them together in a safe place. Remove the wheel and set it aside.
3. Remove the Caliper:
* Locate the Caliper Bolt(s): The caliper is bolted to the caliper bracket. Identify and loosen the caliper bolts using a socket wrench. These are usually 14mm or 15mm.
* Compress the Caliper Piston: Use the caliper piston compression tool to push the piston back into the caliper. This creates space to remove the rotor. If using a C-clamp, be careful not to damage the piston seal. You may need to slightly turn the piston as you compress it.
* Remove the Caliper: Once the piston is compressed, carefully remove the caliper bolts completely and hang the caliper out of the way using a piece of wire or a bungee cord to prevent damage to the brake line. Do not let the caliper hang by the brake line.
4. Remove the Rotor:
* Inspect for Rust or Corrosion: There may be rust or corrosion between the rotor and the hub. If so, use a wire brush or brake cleaner to clean the surfaces.
* Remove the Rotor: Some rotors are held on by a single center bolt, while others may simply slide off. If it's stuck, a rotor removal tool can be very helpful. If using a tool, carefully tap it into place and work the rotor loose. Use caution not to damage the wheel studs. Sometimes a firm tap with a rubber mallet is all that's required.
5. Clean and Inspect: Thoroughly clean the hub mounting surface where the rotor sits. Inspect the rotor for excessive wear, scoring, or cracks. Replace the rotor if necessary.
6. Install the New Rotor (if applicable): If installing a new rotor, carefully slide it onto the hub. Make sure it's flush against the hub.
7. Reinstall Everything:
* Reinstall the Caliper: Reattach the caliper to the bracket and tighten the bolts to the manufacturer's specified torque.
* Reinstall the Wheel: Mount the wheel and tighten the lug nuts in a star pattern (opposite nuts first).
* Lower the Vehicle: Carefully lower the vehicle from the jack stands.
* Torque the Lug Nuts: Finally, torque the lug nuts to the manufacturer's specified torque using a torque wrench.
8. Check for Proper Function: Before driving, check the brake pedal for proper feel and firmness. Pump the brake pedal several times to build pressure. Test the brakes carefully in a safe area before driving normally.
Important Considerations:
* Brake Fluid: Be careful not to spill any brake fluid. If you do, clean it up immediately.
* Caliper Slides: Check the caliper slide pins for smooth movement and lubricate them if necessary.
* ABS Sensor: Be careful not to damage the ABS sensor wire.
* Torque Specifications: Always refer to your vehicle's repair manual for correct torque specifications. Improper torque can lead to failure.
This is a general guide. If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Improperly performed brake work can be dangerous.
