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. Wheel Removal

Use a jack to lift the vehicle and secure it with jack stands.
Remove lug nuts using a socket set.
Take off the wheel to access the brake components.

3. Brake Inspection

Inspect Brake Pads:
- Remove the caliper bolts with a socket set.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang).
- Check the pads for uneven wear or damage; replace if necessary.
Check Brake Rotors:
- Measure rotor thickness with a micrometer. Replace if below minimum specifications.
- Use a runout gauge to check for warping; if warped, replace rotors.

4. Suspension Inspection

Inspect control arms and bushings visually and by hand for any play or damage.
If any components are worn, replace them according to manufacturer specifications.

5. Reassembly

Reattach the brake caliper, ensuring bolts are torqued to manufacturer specifications (typically around 25-30 Nm).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the recommended specification (usually around 120 Nm).
