Here's a breakdown of how to make the job easier, assuming you have some basic mechanical experience:
1. Preparation is Key:
* Gather Tools: You'll need a socket wrench set (metric), a torque wrench (essential!), a C-clamp or brake caliper compressor tool, a wheel chock, jack stands (NEVER work under a vehicle supported only by a jack), wire brush, penetrating oil (like PB Blaster), brake cleaner, and safety glasses. A rotor turning tool can also be helpful.
* Consult a Repair Manual: A Chilton's or Haynes repair manual specific to your 1999 Ford F-150 is invaluable. It provides detailed instructions, torque specifications, and diagrams. This is the single best thing you can do to make the job easier and safer.
* Safety First: Engage the parking brake, chock the wheels, and use jack stands to securely lift the truck. Wear safety glasses to protect your eyes from flying debris.
* Parts: Ensure you have the correct rotors and brake pads for your specific F-150 model. Verify this with the part numbers at an auto parts store.
2. Step-by-Step (Simplified):
1. Wheel Removal: Loosen the lug nuts before jacking up the truck. Remove the wheel.
2. Caliper Removal: Use the caliper compressor tool to push the caliper piston back into the caliper bore. This creates space for the new, thicker rotor. Some calipers can be removed with a single bolt, others have a slide pin that needs to be removed. Your repair manual will show you how. Be prepared for some resistance. Consider using penetrating oil on any stuck bolts beforehand.
3. Rotor Removal: Remove the old rotor. It may be slightly rusted on, so you might need to gently tap it with a hammer and pry bar.
4. Clean and Inspect: Clean the hub thoroughly with a wire brush to remove rust and debris.
5. Rotor Installation: Install the new rotor. Make sure it spins freely and there's no rubbing.
6. Caliper Reinstallation: Carefully reinstall the brake caliper, ensuring the slide pins are lubricated (with caliper grease, NOT brake fluid).
7. Brake Pad Installation: Install new brake pads. These typically just slide in place.
8. Wheel Reinstallation: Put the wheel back on and tighten the lug nuts to the specified torque (found in your repair manual). Don't overtighten!
9. Lower Vehicle: Lower the vehicle carefully using the jack stands.
10. Torque Lug Nuts: Final torque the lug nuts.
11. Pump Brakes: Pump the brake pedal several times to build pressure.
12. Test Drive: Take a short test drive to ensure the brakes are functioning correctly. Listen for unusual noises.
Important Considerations:
* Bleeding Brakes: If you completely remove the caliper from the brake line, you may need to bleed the brakes to remove air bubbles. This is a slightly more advanced procedure, best left to a professional if you're unfamiliar.
* Rust: If your hardware is severely rusted, it might be more efficient to replace the caliper bracket, caliper slide pins, etc. This often makes a cleaner, safer job.
Remember, this is a simplified overview. Your repair manual is your friend. Consult it frequently throughout the process. If you are unsure at any step, stop and seek professional assistance. Brake failure is extremely dangerous.
