Solution

1. Preparation

Tools Required: Wheel chocks, jack stands, lug wrench, torque wrench, brake cleaner, safety glasses, gloves.
Park the vehicle on a level surface, engage the parking brake, and place wheel chocks behind the rear wheels.

2. Lift the Vehicle

Use the jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using the lug wrench.

3. Inspect Brake Components

Brake Pads and Rotors:
- Remove the brake caliper by unscrewing the caliper bolts. Support the caliper with a bungee cord to avoid straining the brake line.
- Inspect the brake pads for even wear. Replace if they are worn unevenly or below the manufacturer's specifications.
- Check the rotors for warping or scoring. Replace if necessary.
Brake Calipers:
- Inspect the calipers for signs of sticking or leakage. If a caliper is malfunctioning, replace it.

4. Check Suspension Components

Look for worn or damaged control arms, bushings, or strut mounts. Replace any defective components.
Ensure that all suspension bolts are tightened to the manufacturer's torque specifications.

5. Reassemble and Test

Reinstall the brake caliper and wheels.
Torque the lug nuts to the manufacturer's specifications.
Lower the vehicle and perform a test drive to confirm that the pulling issue is resolved.
