Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and use wheel chocks.
Allow the vehicle to cool if it has been driven recently.

2. Wheel Removal

Use a lug wrench to loosen the lug nuts on the affected wheel.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Brake Component Inspection

Brake Pads: Remove the caliper bolts using a socket set and slide the caliper off the rotor. Inspect the brake pads for wear; replace if less than 3mm thick.
Brake Rotors: Check the rotor surface for grooves or scoring. If damaged, the rotor should be replaced or resurfaced.
Caliper Functionality: Ensure that the caliper slides freely on its pins. Clean and lubricate the caliper slides if they are sticky.

4. Replacement Procedures

If brake pads are worn, replace them with new pads. Ensure they are installed correctly in the caliper bracket.
If rotors are damaged, install new rotors. Use a torque wrench to tighten the rotor retaining screws to the manufacturer’s specified torque (typically around 10-15 ft-lbs).
Reinstall the caliper, ensuring it is properly seated. Tighten the caliper bolts to the manufacturer's torque specifications (usually around 25-30 ft-lbs).

5. Reassembly

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then use the torque wrench to tighten lug nuts to the manufacturer's specifications (usually 100-150 ft-lbs).

6. Final Check

Conduct a brake fluid check; top off if necessary using the recommended fluid type.
Pump the brake pedal a few times to ensure proper brake pad seating before driving.
