Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during the repair.

2. Remove Wheel

Use a socket set to loosen the lug nuts while the vehicle is still on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Remove the brake caliper bolts using a socket wrench.
Carefully lift the caliper off the rotor without disconnecting the brake line (use a bungee cord to hang it).
Inspect the brake pads for uneven wear and check the caliper guide pins for movement.
If necessary, remove the brake pads and measure their thickness.

4. Replace or Adjust Components

If pads are unevenly worn, replace them with a new set, ensuring they are of the same quality as recommended by the manufacturer.
If calipers are sticking, clean or replace them as needed.
Check brake rotor condition; replace if warped or excessively worn.
Ensure that caliper guide pins are lubricated and functioning properly.

5. Reassemble and Test

Reinstall the caliper over the new brake pads and secure with bolts.
Reattach the wheel and tighten the lug nuts to the manufacturer's specified torque.
Lower the vehicle and reconnect the battery.
