Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Use wheel chocks to prevent movement.

2. Remove Wheel

Using a socket set, loosen the lug nuts on the wheel.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts with a socket set and slide the caliper off the rotor.
- Inspect brake pads for wear; if less than 3mm thick, replace them.
Replacement:
- If replacement is necessary, compress the caliper piston using a C-clamp.
- Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Resurface or Replace Rotors

Check rotors for signs of scoring or warping.
If the rotors are damaged, they should be resurfaced or replaced.
Clean the rotor surface with brake cleaner and a clean rag before reassembly.

5. Reassemble Brake Components

Reinstall the brake caliper and tighten the caliper bolts to the manufacturer's torque specifications (typically 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Final Checks

Lower the vehicle and tighten the lug nuts to the specified torque value (usually 100-120 ft-lbs).
Test the brakes by pressing the pedal a few times to ensure proper seating of components.
