The utility model relates to the technical field of braking, in particular to a pair of calipers, which comprises a caliper body and a piston mechanism, the piston mechanism comprises a push rod part and a piston cylinder, a sealing cavity is formed between the front end of the push rod part and the cylinder wall of the piston cylinder, and the sealing cavity is communicated with an air guide groove arranged at the front end of the push rod part. The caliper further comprises a brake mechanism used for enabling the piston mechanism to move, the piston mechanism is arranged in the caliper body, when the brake mechanism pushes the piston mechanism, the piston mechanism can move relative to the caliper body, one end of the piston cylinder is closed, the front end of the push rod part is embedded in the piston cylinder and can reciprocate in the piston cylinder, and an air guide groove is formed in the cylinder wall of the piston cylinder. The sealing cavity can be communicated with the outside through the air gu
