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

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully lift the caliper off the rotor and support it without stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any damage or sticking.
5. Install new brake pads into the caliper bracket.
Tools Required: Socket set, torque wrench, brake pad spreader.

4. Inspect and Replace Rotors (if necessary)

Sub-steps:
