BRAKE CALIPER ASSEMBLY, BRAKE AND VEHICLE

The disclosure relates to the technical field of vehicles, and particularly provides a brake caliper assembly, a brake, and a vehicle, aiming to solve the problem of how to increase the maximum deflection that a leaf spring can bear on the premise of ensuring an elastic restoring force of the leaf spring. The brake caliper assembly of the disclosure comprises a leaf spring arranged between a first brake caliper and a second brake caliper. The leaf spring comprises an elastic structure. The elastic structure comprises a bending portion, an extending portion, an outward-expanding portion, and an abutting portion that are connected in sequence; the outward-expanding portion extends to the outside of the leaf spring from the extending portion, the bending portion is bent inwards, and the abutting portion abuts on the first brake caliper and/or the second brake caliper. According to the disclosure, the maximum deflection that the leaf spring can bear can be increased on the premise of ensuring the elastic restoring force of the leaf spring.
