- Loosen the lug nuts using a socket wrench.
- Lift the vehicle with a jack and secure it with jack stands.
- Remove the lug nuts completely and take off the wheel.
Tools Required:
- Jack and jack stands
- Lug wrench

3. Remove the Brake Caliper

Sub-steps:
- Locate the caliper mounting bolts and remove them using a socket wrench.
- Carefully slide the caliper off the brake rotor. Do not let it hang by the brake line.
- Support the caliper with a bungee cord or similar device.
