Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
- Loosen the lug nuts slightly while the wheel is still on the ground.
- Lift the vehicle with the jack and secure it with jack stands.
- Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Tools Required: Visual inspection tools, flashlight.
Sub-steps:
- Examine the brake pads for uneven wear (one side thinner than the other).
- Inspect the rotors for grooves or uneven surfaces.
- Check the caliper for binding or any signs of leakage.

4. Replace Components as Needed

Tools Required: Socket set, torque wrench, brake cleaner.
Sub-steps:
- If brake pads are worn unevenly, replace them in pairs (front or rear, depending on which are affected).
- If rotors are damaged, replace them as well.
- Clean the caliper slides and apply anti-seize lubricant to ensure smooth operation.

5. Reassemble and Test

Tools Required: Torque wrench.
Sub-steps:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
- Test the brakes by pressing the pedal several times to seat the pads.
