Solution

1. Preparation

Tools Required: Socket set, torque wrench, brake cleaner, lug wrench, jack stands, brake pad spreader
Secure the vehicle on a flat surface and ensure it is in "Park" mode.
Disconnect the negative battery terminal to avoid electrical issues during repairs.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel with uneven brake wear.
Lift the vehicle using a jack and support it securely with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
2. Inspect the brake pads; if they are unevenly worn, remove them from the caliper bracket.
3. Clean the caliper bracket with brake cleaner to remove dust and debris.
4. Install new brake pads ensuring they are the correct thickness and fit.
5. Apply brake grease to the back of the pads to minimize noise and improve performance.

4. Check Caliper and Rotor

Inspect the caliper for sticking or malfunctioning components. If necessary, rebuild or replace the caliper.
Check the rotor for any signs of warping or excessive wear. If damaged, resurface or replace the rotor.
Reinstall the caliper by sliding it back over the rotor and securing it with bolts. Torque to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
Reconnect the negative battery terminal and check the brake fluid level. Top off if necessary.
Test the brakes gently to ensure proper operation before returning to normal driving conditions.
