Solution

1. Preparation

Gather tools and parts for the job.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel: Use a jack to lift the vehicle and secure it with jack stands. Remove the wheel using a socket set.
2. Inspect brake pads: Check the thickness of the brake pads on both sides; replace if uneven wear is found.
3. Replace brake pads (if necessary):
  - Remove caliper bolts and slide the caliper off the rotor.
  - Replace the pads ensuring they are properly seated. Use quality aftermarket or OEM pads.
  - Reinstall the caliper and torque the bolts to manufacturer specifications (usually around 25-30 Nm).

3. Check and Adjust Wheel Alignment

Sub-steps:
1. Perform alignment check: Use alignment equipment to measure camber, caster, and toe angles.
2. Adjust alignment: Follow manufacturer specifications to adjust alignment settings if they are out of spec.

4. Inspect Suspension Components

Sub-steps:
1. Check for wear: Inspect control arms, bushings, and tie rods for signs of wear or damage.
2. Replace any damaged components: Use appropriate tools to remove and install new parts, torquing to specifications.
