The brake is conventionally applied in a manner that a user pinches the brake lever 11, the brake lever 11 pulls the brake element 20 through the brake cable 30, the brake element 20 can be tightly attached to a wheel or a disc 40 fixedly arranged on the side surface of the wheel, and friction generated by the contact between the brake element 20 and the disc 40 provides a braking force to reduce the speed of the vehicle. Since the braking force for decelerating the vehicle is mainly provided by the friction force generated by the contact between the brake member 20 and the disc 40, the braking force for decelerating the vehicle is positively correlated with the pressure applied to the disc 40 from the brake member 20 under the condition that the friction coefficient is unchanged.
The amount of pressure that can be generated by the brake element 20 under normal conditions depends on the stroke of the lever 11: the longer the stroke of the brake lever 11 is, the greater the moving distance of the brake cable 30 is, and the pressure and friction force of the brake component 20 on the disc 40 are correspondingly increased, and the better the braking effect is.
