Solution

1. Preparation

Gather tools: socket set, jack stands, torque wrench, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Loosen the lug nuts on the front left wheel.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the wheel to access the brake assembly.
4. Inspect the brake pads for uneven wear; replace if one side is significantly thinner.
5. Use brake cleaner to clean the caliper and rotor.
6. Install new brake pads, ensuring they are seated correctly.
7. Reinstall the wheel and torque the lug nuts to manufacturer specifications.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If the rotors are warped or below the minimum thickness, remove them by unbolting the caliper and rotor.
2. Install new rotors, ensuring they are clean and free from debris.
3. Reinstall the caliper and torque the bolts to the specified torque value.

4. Perform Wheel Alignment

Sub-steps:
1. Take the vehicle to a certified alignment shop.
2. Ensure that the alignment is adjusted according to manufacturer specifications.
3. Check for any worn suspension components that may need replacement.
