Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect the brake pads for wear; if pads are worn unevenly, replace them.
3. If replacing, remove caliper bolts and slide the caliper off the rotor.
4. Replace old pads with new ones, ensuring proper orientation.
5. Reinstall the caliper and torque bolts to manufacturer specifications (typically around 25-35 ft-lbs).

3. Check and Replace Brake Rotors (if necessary)

Sub-steps:
1. Inspect rotors for warping or uneven surfaces.
2. If damaged, remove the rotor by unscrewing the retaining screws.
3. Install new rotors and torque screws to manufacturer specifications (usually around 10-15 ft-lbs).

4. Caliper Inspection and Cleaning

Sub-steps:
1. Inspect calipers for signs of leakage or sticking pistons.
2. Clean any dust and debris from the caliper.
3. If calipers are sticking, consider rebuilding or replacing them.

5. Wheel Alignment

Sub-steps:
1. Lift the vehicle and inspect suspension components for damage.
2. Take the vehicle to a professional alignment shop.
3. Have the alignment adjusted to manufacturer specifications.
