Brake caliper sealing performance detection member

The utility model discloses a brake caliper sealing performance detection member which comprises a main body, an air inlet interface and a connecting cover body. An air inlet hole is formed in the main body, a cavity is formed in the connecting cover body, and the connecting cover body is connected to the main body and covers the air inlet hole; and the air inlet interface is arranged on the connecting cover body. When in use, the main body is fixedly connected with a brake caliper to be detected, the air inlet hole on the main body is aligned with an opening of the brake caliper, and the air inlet interface is connected with an air inlet pipeline for air intake. If the air pressure in the brake caliper can be kept at a certain air pressure for a long time after ventilation, the sealing performance of the brake caliper is good, and the brake caliper does not need to be disassembled for inspection or maintenance. And if the air pressure in the brake caliper cannot be kept, the sealing performance of the brake
