Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, measuring caliper, safety glasses, gloves.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Raise the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on where the uneven wear is observed.
Secure the vehicle with jack stands.

3. Remove Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Place the wheel aside safely.

4. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper by unscrewing the caliper bolts with the socket set.
- Slide the caliper off the rotor and support it without stressing the brake line.
- Remove the old brake pads from the caliper bracket.
- Inspect the caliper for sticking pistons or damage.
- If necessary, compress the caliper piston using a C-clamp.
- Install new brake pads ensuring they match the specifications of the vehicle.

5. Inspect and Replace Brake Rotors (if needed)

If the rotors show uneven wear or are below the minimum thickness, replace them.
Remove the caliper bracket and rotor.
Install the new rotor, ensuring it is clean and free from contaminants.
Reattach the caliper bracket and torque to manufacturer specifications.

6. Reassemble and Lower Vehicle

Reattach the caliper and torque the bolts to specifications.
Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts in a crisscross pattern to the specified torque.

7. Final Checks

Reconnect the negative battery terminal.
Test the brakes by pressing the brake pedal a few times to ensure proper operation.
