Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Check for wear indicators on the brake pads. Replace if worn beyond manufacturer specifications.
Inspect Brake Rotors:
- Measure rotor thickness with a micrometer. If below minimum thickness, replace rotors.
- Look for warping or scoring on the rotor surface. If warped, replace rotors.
Install New Brake Pads and Rotors:
- Remove caliper bolts and slide off the caliper.
- Remove old pads and replace with new ones.
- If replacing rotors, remove the old rotor and install the new one, ensuring proper torque specifications are followed (usually between 80-100 ft-lbs for rotor bolts).

4. Reassemble

Reattach the brake caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then tighten the lug nuts in a star pattern to the specified torque.

5. Final Checks

Inspect suspension components for any signs of damage or excessive wear.
Ensure all connections are secure and check brake fluid levels.
