Brake clamp

The utility model particularly relates to a brake clamp which comprises a clamp lever and a brake pad assembly hinged to one end of the clamp lever, and further comprises a pin shaft sensor arranged at the hinged position of the clamp lever and the brake pad assembly and a data processing device in communication connection with the pin shaft sensor. The brake pad assembly is hinged to the clamp lever through the pin shaft sensor. According to the brake clamp provided by the utility model, the pin shaft sensor plays a role in connecting the clamp lever and the brake pad assembly, and meanwhile, the clamping force borne by the brake pad assembly is detected. And the data collector in communication connection with the pin shaft sensor is used for acquiring the numerical value of the clamping force and judging and analyzing the reason of the abnormal problem according to the relationship between the acquired numerical value of the clamping force and the numerical value of the braking force generated by the brake
