Here's a general outline. Specific steps may vary slightly depending on your Expedition's trim level and whether it has anti-lock brakes (ABS). Always consult your vehicle's repair manual for detailed instructions specific to your model.
Tools You'll Need:
* Jack and jack stands (crucial for safety)
* Lug wrench
* Wheel chocks
* Socket wrench set (metric)
* Torque wrench
* C-clamp or caliper compression tool
* Brake caliper slide pin lubricant
* Wire brush or brake cleaner
* Rotor removal tool (optional, but highly recommended)
* New brake rotors (ensure correct size and fitment for your Expedition)
* New brake pads (recommended to replace these at the same time)
* Gloves
* Safety glasses
Steps:
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks on the wheels opposite the one you're working on. Raise the vehicle using the jack and securely support it with jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and carefully take off the wheel.
3. Remove the Caliper:
* Option 1 (Easier, if applicable): Some models allow you to simply use a C-clamp or caliper compression tool to push the caliper piston back in. This will give you enough space to remove the rotor. Be careful not to damage the caliper or piston seal.
* Option 2 (More Common): You might need to unbolt the caliper from the caliper bracket. Support the caliper with a wire or bungee cord to prevent it from hanging by the brake line. This prevents stressing the brake line.
4. Remove the Rotor: This is often the trickiest part. Sometimes the rotor simply slides off; other times it might be rusted or seized to the hub. A rotor removal tool can be invaluable here. If you don't have one, you might need to gently tap around the rotor's edges with a hammer and punch to break it free. Be careful not to damage the wheel hub.
5. Clean the Hub: Use a wire brush or brake cleaner to thoroughly clean the wheel hub mating surface where the rotor sits. This ensures a proper fit for the new rotor.
6. Install the New Rotor: Slide the new rotor onto the wheel studs. Ensure it sits flush against the hub.
7. Reinstall the Caliper: Reinstall the caliper onto its bracket, ensuring the brake pads are correctly seated. Lubricate the caliper slide pins with brake caliper slide pin lubricant.
8. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts to the manufacturer's specified torque (check your owner's manual or a torque specification chart).
9. Lower the Vehicle: Carefully lower the vehicle to the ground.
10. Final Check: Pump the brake pedal several times to ensure proper engagement. Test drive the vehicle cautiously, checking for unusual noises or vibrations.
Important Considerations:
* Brake Pad Replacement: It's highly recommended to replace your brake pads at the same time as the rotors. This ensures even braking and prevents premature wear on the new rotors.
* Torque Specifications: Always use a torque wrench to tighten the lug nuts and caliper bolts to the manufacturer's specifications. Over-tightening can damage components.
* ABS Sensors: If your Expedition has ABS, be careful not to damage the ABS sensor during the rotor replacement process.
* Professional Help: If you encounter any significant difficulties, or if you're unsure about any step, take your vehicle to a qualified mechanic. Improper brake repair can be dangerous.
