Tools You'll Need:
* Jack and jack stands: Safely lift the truck and support it securely.
* Wheel chocks: Place these on the wheels that remain on the ground.
* Lug wrench: Remove the wheel.
* Socket wrench and sockets: Appropriate sizes for caliper bolts, rotor retaining bolts (if any), and possibly axle nut.
* C-clamp or brake caliper compression tool: To compress the brake caliper piston.
* Hammer and drift punch (optional): If the rotor is stuck.
* Penetrating lubricant (PB Blaster or similar): To help loosen rusted bolts.
* Gloves and safety glasses: Protect yourself.
* Torque wrench: To properly tighten bolts during reassembly.
Procedure:
1. Safety First: Engage the parking brake, chock the wheels, and use jack stands to safely lift the truck. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Use the lug wrench to remove the wheel nuts and take off the wheel.
3. Compress the Caliper Piston: Use a C-clamp or caliper compression tool to push the brake caliper piston back into the caliper. This will give you the clearance needed to remove the rotor. Be careful not to damage the piston or the caliper seal. Some calipers have a bleeder valve you can open to allow fluid to escape more easily as you compress the piston. It's a good idea to replenish any brake fluid that's lost.
4. Remove the Caliper: Once the piston is compressed, you may need to carefully remove the caliper. This usually involves removing one or two bolts that hold the caliper to the caliper bracket. Support the caliper with a wire or bungee cord to prevent it from hanging by the brake hose. Do not let the brake hose hang freely.
5. Remove the Rotor: Most F-150 rotors are held in place by friction and may slide off once the caliper is removed. Sometimes there are small retaining screws or clips on the back of the rotor, which should be removed first. If the rotor is stuck, gently tap it off with a hammer and drift punch. Start tapping gently around the circumference. Avoid damaging the rotor's mounting surface on the hub.
6. Clean the Hub: Once the rotor is off, clean the mating surfaces of the hub and the new rotor. Remove any rust or debris.
7. Installation (Reverse Order): Install the new rotor, caliper, and wheel in reverse order of removal. Make sure to tighten all the bolts according to the manufacturer's specifications in your vehicle's repair manual.
Important Considerations:
* Rust: If the rotor is heavily rusted, it will be harder to remove. Apply penetrating lubricant generously to any bolts and let it soak for a while before attempting removal.
* Hub Corrosion: Inspect the wheel hub for corrosion and clean it thoroughly.
* Brake Pads: Check the brake pads' condition while the caliper is removed and replace them if necessary.
* Torque Specifications: Use a torque wrench and follow the torque specifications listed in your owner's manual or a repair manual for your specific vehicle year and model. Incorrect torque can damage the components or lead to brake failure.
If you're not comfortable performing this task, it's best to take your F-150 to a qualified mechanic. Brake work is critical for safety.
