Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Use jack stands to secure the vehicle after lifting.

2. Remove Wheel Assembly

Sub-steps:
- Loosen lug nuts with a socket set before lifting the vehicle.
- Raise the vehicle using a floor jack and secure it with jack stands.
- Remove the wheel by taking off the lug nuts completely.
Tools Required: Socket set, floor jack, jack stands.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the brake caliper by loosening the caliper bolts and sliding it off the rotor.
- Inspect the brake pads for uneven wear; if they are worn unevenly, replace them.
- Compress the caliper piston using a brake caliper tool before installing new pads.
- Place new brake pads into the caliper bracket ensuring they are seated properly.
- Reinstall the brake caliper and tighten bolts to manufacturer specifications (generally 25-35 lb-ft).
Tools Required: Brake caliper tool, torque wrench.

4. Rotor Inspection/Replacement

Sub-steps:
- Inspect the brake rotor for grooves or warping. If damaged, replace the rotor.
- Clean the rotor surface with brake cleaner before installation.
- If replacing, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Install new rotors by aligning them and tightening retaining screws to manufacturer specifications.
Tools Required: Brake cleaner, screwdrivers, torque wrench.

5. Reassemble Wheel Assembly

Sub-steps:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle from the jack stands using the floor jack.
- Tighten the lug nuts to the specified torque (generally 80-100 lb-ft).
Tools Required: Torque wrench.
