Solution

1. Preparation

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

2. Inspect and Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel using a socket set.

3. Brake Pad and Rotor Inspection

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor; do not let it hang by the brake line.
- Check the thickness of the brake pads. Replace if worn down to the manufacturer's minimum specification.
Inspect Brake Rotors:
- Examine the rotors for grooves or uneven wear.
- If the rotors are significantly scored or warped, they should be replaced or machined to ensure a smooth surface.

4. Replace Components (if necessary)

Brake Pad Replacement:
- Remove the old pads and install new ones.
- Ensure the new pads are properly seated in the caliper bracket.
Rotor Replacement (if applicable):
- Remove the old rotor and install the new rotor.
- Torque the rotor retaining screws to the manufacturer's specifications.

5. Reassemble Components

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Reconnect the negative battery terminal.
