The double-caliper pneumatic disc brake comprises a brake disc, two brake calipers arranged on the side of the brake disc, an air chamber, an eccentric rotating arm, an eccentric rotating arm installation base and a fixing plate, the fixing plate is fixedly installed on an axle housing, supports of the two brake calipers are installed on the fixing plate, and the two brake calipers are installed on the air chamber. Moving calipers of the two brake calipers are installed on the support in a sliding mode through guide shafts, eccentric rotating arm installation bases are fixed to the end faces of the outer sides of the moving calipers, eccentric rotating arms are in a Y shape, air chambers are connected with the trunk ends of the eccentric rotating arms, and the two branch ends of the eccentric rotating arms are hinged to the eccentric rotating arm installation bases through rotating pins respectively. Protruding pin rollers are movably arranged at the two branch ends of the eccentric rotating arm respectively, the eccentric rotating arm is in movable contact with piston body assemblies of the double brake calipers through the pin rollers respectively, and return springs are arranged between first friction plates of the double brake calipers and the movable calipers. According to the invention, simultaneous braking of the double brake calipers and automatic compensation of the friction plates are realized, and the braking effect is improved.
