Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, brake cleaner, and a torque wrench.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid any electrical issues during repair.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts on the wheel(s) with uneven wear.
Jack up the vehicle and secure it with jack stands.
Remove the wheel(s) to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the rotor, supporting it so it doesn't hang by the brake line.
Remove the old brake pads from the caliper bracket.
Clean the caliper and bracket area with brake cleaner.
Inspect the caliper slides and lubricate them with brake grease if necessary.
Install the new brake pads, ensuring they fit snugly into the caliper bracket.

4. Reassemble and Adjust

Reposition the caliper over the new brake pads and torque the caliper bolts to the manufacturer’s specifications (usually around 20-30 ft-lbs).
Reinstall the wheel(s) and hand-tighten the lug nuts.
Lower the vehicle and use the torque wrench to properly torque the lug nuts (80-100 ft-lbs typically).

5. Final Checks

Reconnect the battery.
Pump the brake pedal to ensure proper pad seating against the rotor.
Test drive to ensure brakes function correctly without pulling or noise.
