Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is still on the ground.
2. Jack up the front of the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Tools Required: Torque wrench, brake cleaner, socket set.
Sub-steps:
1. Inspect the brake rotors for any signs of warping or scoring. Replace if necessary.
  - If warped, replace with new rotors, ensuring they meet OEM specifications.
2. Check brake pads for thickness; replace if they are below the minimum thickness (usually around 3mm).
3. Clean the rotor surfaces and caliper mounting points with brake cleaner.
4. Reinstall new pads and rotors as per manufacturer specifications, using a torque wrench to tighten bolts to the recommended torque settings.

4. Check and Adjust Wheel Alignment

Tools Required: Alignment tools or access to an alignment rack.
Sub-steps:
1. Take the vehicle to a professional alignment shop to ensure proper alignment.
2. Adjust camber, caster, and toe as necessary according to manufacturer specifications.

5. Reinstall Wheel and Test

Tools Required: Lug wrench, torque wrench.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and torque lug nuts to the specified value.
3. Repeat the process on the other front wheel if necessary.
