3. Remove the lug nuts and take off the wheel.
Tools Required: Lug wrench, jack, jack stands

3. Brake Pad Replacement

Sub-steps:
1. Remove the caliper bolts using a socket set to access the brake pads.
2. Carefully slide the caliper off the rotor and support it with a bungee cord or rope to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads into the bracket, ensuring they are properly aligned.
Tools Required: Socket set, bungee cord

4. Rotor Inspection and Replacement
