In a traditional drum braking system, the caliper works in cooperation with the brake drum; while in a modern disc braking system, the caliper directly clamps the metal brake disc located at the center of the wheel. An automotive caliper testing device is a special equipment for measuring and evaluating the performance of the brake caliper. The size, braking force, durability, friction coefficient, and high and low pressure sealing performance of the automotive caliper all need to be detected. An existing device for testing the high and low pressure sealing performance of an automotive caliper is to place the automotive caliper in a testing chamber, connect the caliper and the pipeline interface of the device through an oil pipe, close the explosion-proof door, open the valve, and the hydraulic oil in the device flows to the automotive caliper. By observing the pressure gauge, the high and low pressure sealing performance of the automotive caliper is tested.
