2. Clean brake pads and rotors: Use a wire brush to remove any dirt or debris from the surface of the brake pads. Then, clean the brake rotors with brake cleaner and a clean rag.
3. Apply brake grease: Apply a small amount of brake grease to the back of the brake pads and the contact points on the brake rotors. This will help reduce friction and prevent the brakes from squeaking.
4. Reassemble the brakes: Reinstall the brake pads and any other components you removed. Tighten all of the bolts and screws securely.
5. Test the brakes: Take the mini bike for a short ride to test the brakes. If the brakes are still squeaking, you may need to repeat the process or have a professional mechanic take a look at the brakes.
