2. Remove Wheel

Sub-steps:
1. Loosen wheel lug nuts with a lug wrench.
2. Raise the vehicle using a hydraulic jack.
3. Secure the vehicle with jack stands.
4. Remove the lug nuts and take off the wheel.
Tools Required: Lug wrench, hydraulic jack, jack stands

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts with a socket set.
2. Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
