Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts using a lug wrench.
2. Raise the vehicle with a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper by unbolting it from the bracket (typically requires a socket).
2. Slide the caliper off the rotor and secure it with a bungee cord (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are correctly oriented.
5. Reattach the caliper over the new pads and tighten the bolts to the manufacturer's torque specification (usually around 25-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for scoring or warping.
2. If replacement is needed, remove the caliper bracket (additional bolts may need to be removed).
3. Slide the rotor off the hub.
4. Install new rotor, ensuring proper alignment.
5. Reattach the caliper bracket and torque to specification.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque (typically 76-80 ft-lbs).
3. Pump the brake pedal several times to seat the pads against the rotors.
