Improper use of the brake ruins both the wheels and the brake itself. The function of a brake on a freestyle scooter is different than, for example, on bicycles or commuting scooters.
The brake is intended for performing tricks and slowing down.
The purpose of the brake is not to stomp on it and hold it down for 10 minutes while riding to school.
Improper use of the brake will create flat spots on the wheel. And you can even break the brake itself.
If you want to stop, jump off or use your foot (shoe).
