Generally speaking, the brakes attached to roller skates can only be used for jogging, and can only play a slow braking effect, such as the rear brakes of bicycles. But when it is necessary to brake immediately, it is difficult to meet the needs.
1. Roller skaters must learn T-brakes or other braking actions that do not depend on brakes before they can unload the brakes.
Generally speaking, the brake is connected with the last wheel, so the nail penetration of the last wheel is longer than that of the first three wheels. After the brake is removed, there must be a nail with the same length as the first three wheels to replace the last nail.
