Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts on the affected wheel, but do not remove them completely.
2. Use a jack to lift the vehicle and then secure it with jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Sub-steps:
1. Visually inspect brake pads for wear. Replace if they are below the manufacturer's recommended thickness (typically 3mm).
2. Check brake rotors for grooves or scoring. If damaged, they should be resurfaced or replaced.
3. Ensure calipers are not stuck. If necessary, remove and clean them.

4. Replace Brake Pads and/or Rotors

Sub-steps:
1. If replacing pads, remove the caliper bolts and slide the caliper off the rotor.
2. Remove the old pads and install new ones, ensuring they are properly aligned.
3. If replacing rotors, remove the rotor and install the new rotor, ensuring to torque the retaining screws to manufacturer specifications.
4. Reinstall the caliper and torque bolts to the specified torque value (e.g., 25-30 ft-lbs).

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (e.g., 100-120 ft-lbs).
2. Lower the vehicle and reconnect the negative battery terminal.
3. Pump the brake pedal a few times to seat the new pads.
