Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure personal safety equipment is worn (gloves, eye protection).

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel completely.

3. Inspect and Replace Brake Rotors

Inspect for Warping:
- Use a runout gauge to check the rotor for warpage. If the runout exceeds specifications (generally 0.002 inches), replacement is necessary.
Remove Brake Caliper:
- Unbolt the caliper from the bracket using a socket set.
- Support the caliper with a bungee cord to avoid straining the brake line.
Remove Rotor:
- If the rotor is held by screws, remove them using a screwdriver.
- Slide the rotor off the hub. If stuck, gently tap with a rubber mallet.
Install New Rotor:
- Clean the new rotor with brake cleaner to remove any protective oil.
- Slide the new rotor onto the hub.

4. Replace Brake Pads

Remove Old Pads:
- Remove the caliper bracket if necessary, then pull out the old brake pads.
Install New Pads:
- Lubricate the backing of the new pads with brake grease.
- Install the new pads into the caliper bracket.

5. Reassemble

Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque the lug nuts to the proper specification (usually around 90-100 ft-lbs).
