Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspection: Remove brake caliper by unbolting it from the bracket. Check the brake pads for thickness; if they are worn below the manufacturer's specification (usually 3mm), proceed with replacement.
Replacement: Remove old pads and install new ones, ensuring they are seated correctly in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspection: Check the rotors for grooves or scoring. If damaged beyond specification, replace the rotors.
Replacement: Remove the old rotors by unbolting them from the hub. Install new rotors, ensuring they are torqued to the manufacturer's specifications (typically 75-90 ft-lbs for most vehicles).

5. Reassemble and Reinstall Wheel

Reattach the brake caliper over the new pads and the rotor.
Reinstall the wheel and tighten lug nuts to the specified torque.
