Tools You'll Need:
* Jack and jack stands: Essential for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the other wheels.
* Lug wrench: To remove the wheel.
* Socket set and ratchet: Various sizes, including those needed for caliper bolts, rotor retaining bolts (if any), and possibly the caliper bracket bolts.
* C-clamp or caliper compression tool: To compress the brake caliper piston.
* Torque wrench: Absolutely necessary for proper tightening of bolts.
* Penetrating oil (PB Blaster or similar): Helps loosen rusted bolts.
* Wrench for caliper bracket bolts (if needed): Some models require removing the caliper bracket.
* Clean rags or shop towels: To keep things clean and prevent brake fluid contamination.
* New brake rotor: Make sure you get the correct one for your specific F-150 model.
* Gloves: Protect your hands.
* Safety Glasses: Protect your eyes from flying debris.
Procedure:
1. Safety First: Engage the parking brake, chock the rear wheels, and jack up the front of the truck. Securely support it on jack stands.
2. Remove the Wheel: Remove the lug nuts and carefully take off the wheel.
3. Remove the Caliper:
* Option 1 (Most Common): Use the C-clamp or caliper compression tool to push the caliper piston back into the caliper. This gives you enough room to remove the rotor. Be careful not to damage the piston seal. You may need to carefully twist the piston as you push to help it seat properly. Some brake fluid might leak, so have rags ready. Once the piston is compressed sufficiently, you can either carefully hang the caliper using a wire or bungee cord out of the way, or use a zip tie to secure it to something nearby. Avoid letting the caliper hang by the brake line.
* Option 2 (Some Models): You might need to remove the caliper bracket bolts to completely remove the caliper assembly. This involves removing the bolts holding the bracket to the knuckle, then carefully removing the bracket with the caliper attached.
4. Remove the Rotor: The rotor may simply slide off after the caliper is removed. Sometimes there are retaining bolts or screws holding the rotor to the hub. If so, remove those bolts. If the rotor is stuck, carefully tap it from behind with a hammer and a block of wood to dislodge it. Avoid damaging the wheel studs.
5. Install the New Rotor: Carefully slide the new rotor onto the wheel studs. Ensure it's seated correctly. If there were retaining bolts, reinstall them to the proper torque.
6. Reinstall the Caliper: Carefully reinstall the caliper, ensuring the brake pads are properly seated against the rotor. If you removed the caliper bracket in step 3, reinstall the bracket. Tighten all bolts to the manufacturer's specifications.
7. Reinstall the Wheel: Put the wheel back on, tighten the lug nuts, and lower the truck.
8. Final Check: After lowering the truck, tighten the lug nuts again to specification. Pump the brake pedal several times to ensure the brakes are functioning properly. Take a test drive at low speeds to further check for proper braking and any unusual noises.
Important Notes:
* Brake Fluid: If you have to completely remove the caliper you might get some brake fluid out. Brake fluid is corrosive and harms paint. Clean up any spills immediately.
* Bleeding Brakes: In some cases, especially if the caliper was fully removed, you might need to bleed the brakes to remove any air that may have entered the system. This requires a helper and a bleeding kit.
* Torque Specifications: Use a torque wrench and follow the manufacturer's specifications for all fasteners. Over-tightening can strip threads, under-tightening can lead to loosening and brake failure.
* Professional Help: If you're not comfortable with this procedure, it's best to take your truck to a qualified mechanic. Brake work is critical for safety.
This is a general guide. Variations exist depending on your specific F-150 model. Consult your vehicle's repair manual for the most accurate and detailed instructions.
