Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle with a jack and secure with jack stands.
3. Remove lug nuts completely and take off the wheel.
Tools Required:
- Jack and jack stands
- Lug wrench

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set and carefully lift the caliper off the rotor.
2. Slide out the old brake pads from the caliper bracket.
3. Inspect the caliper for wear and ensure the pistons are functioning properly.
4. Install new brake pads, ensuring they are properly aligned.
5. Reattach the caliper and torque the bolts to the manufacturer's specifications (typically around 20-25 ft-lbs).
Tools Required:
- Socket set
- Torque wrench

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If the rotors are damaged or worn, remove the caliper bracket by unscrewing its bolts.
2. Slide the rotor off the hub; if it's stuck, gently tap it with a rubber mallet.
3. Install the new rotor, ensuring it is seated flush against the hub.
4. Reattach the caliper bracket and torque to specification.
Parts Required:
- Brake pads (if worn)
- Brake rotors (if damaged)

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle off jack stands and tighten lug nuts to the specified torque (typically 75-90 ft-lbs).
3. Pump the brake pedal to seat the pads before driving.
Tools Required:
- Torque wrench
