Solution

1. Preparation

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

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure it with jack stands for safety.

3. Inspect and Replace Brake Components

Brake Rotor Inspection:
- Remove the wheel using a socket set.
- Inspect rotors for warping; if warped (more than 0.002 inches), replace them.
- If rotors are within specification but show uneven wear, consider resurfacing them.
Brake Pad Inspection:
- Remove the caliper bolts with a socket set.
- Slide the caliper off and inspect the pads; replace if less than 3mm thick or if damaged.

4. Suspension Check

Inspect control arms and bushings for cracks or excessive play.
If any components are worn, replace them according to manufacturer specifications.

5. Reassemble and Lower Vehicle

Reinstall the caliper and wheel, ensuring all bolts are torqued to manufacturer specifications.
Lower the vehicle from the jack stands and remove the jack.
