[0031] Example: According to the instruction manual attached Figures 1-4 It can be seen that by fixing the brake caliper 1 to the vehicle body and the brake disc 3 to the main shaft, the device is fixed. When braking is required, a pair of pistons 21 are driven by a hydraulic, pneumatic or electric power device to squeeze towards the center inside the brake caliper 1. As the two brake pads 22 gradually approach the brake disc 3, the magnetic block 23 and the sensing metal ring 4 also continuously approach each other, generating a magnetic eddy current effect, which decelerates the main shaft.
