Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if working with electronic brake components.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors
- Remove the wheel using a socket set.
- Inspect brake pads for thickness; replace if less than 3mm.
- Measure rotor thickness with a micrometer; replace if below manufacturer specifications or if warping is evident.
Replace Brake Pads
- Remove caliper bolts and lift the caliper off the rotor.
- Replace old pads with new ones, ensuring they are oriented correctly.
- Reinstall the caliper and torque bolts to manufacturer specifications.
Replace Rotors (if necessary)
- Remove the rotor from the hub by tapping with a hammer if stuck.
- Clean the hub surface before installing a new rotor.
- Install the new rotor and torque to specifications.

3. Perform Wheel Alignment

Use a wheel alignment machine to check and adjust the alignment.
Adjust camber, caster, and toe settings to manufacturer specifications.

4. Inspect and Repair Suspension Components

Visually inspect suspension components such as control arms, bushings, and struts for wear.
Replace any damaged components as needed, following manufacturer repair procedures.

5. Tire Inspection and Rotation

Check tire pressure; inflate to manufacturer specifications.
Inspect tires for uneven wear; replace if necessary.
Rotate tires if applicable to promote even wear.
