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 Brake Components

Sub-steps:
1. Examine the brake pads for minimum thickness; replace if worn down.
2. Check the rotor surface for any grooves or excessive wear; replace if necessary.
3. Ensure calipers are not sticking and move freely.
Tools Required: Caliper tool, socket set.

4. Replace Brake Pads (if necessary)

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor.
3. Remove old brake pads and install new ones (ensure they are oriented correctly).
4. Reattach the caliper and torque bolts to the manufacturer's specifications.
Tools Required: Torque wrench, socket set.

5. Reassemble and Test

Sub-steps:
