Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, caliper tool, and safety goggles.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on which brake pads are worn unevenly.
Secure the vehicle with jack stands to ensure stability.

3. Remove Wheel

Use the lug wrench to loosen and remove the lug nuts.
Carefully take off the wheel to access the brake system.

4. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using the appropriate socket.
- Note: Support the caliper with a bungee cord to avoid straining the brake line.
Inspect the brake pads for uneven wear; replace if necessary.
Sub-steps:
- If replacing, compress the caliper piston using a caliper tool.
- Install new brake pads, ensuring they are properly seated in the caliper bracket.

5. Inspect Rotors and Calipers

Check the rotors for any signs of wear or damage (warping, scoring).
If needed, resurface or replace rotors according to the manufacturer’s specifications.
Inspect calipers for proper functionality; replace if they do not slide freely.

6. Reassemble and Recheck

Reinstall the caliper and secure it with the caliper bolts. Use a torque wrench to tighten bolts to the manufacturer's specified torque value.
Reattach the wheel and tighten the lug nuts in a crisscross pattern.
Lower the vehicle back to the ground and reconnect the battery.
