A disc brake comprises a body arranged on a spring-loaded frame of the vehicle with a tong parallel-link motion, an amplification mechanism, shoes and friction pads interacting with the brake disc. The tong parallel-link mechanism is made by H-shaped levers. The body is made as a monoblock body with two coaxially arranged braking cylinders of a service and automatic parking brake. The body may freely rotate on an axis located horizontally in the plane of braking disc rotation. The amplification mechanism is located inside the monoblock body and is made as single-link in the form of a swinging stem contacting with a leash. The piston of the service brake is made with a stiffly attached guide and a swinging stem, and the piston of the automatic parking brake is equipped with a stem having a plug, a nut and a bolt. The stem with the plug acts at the service brake piston, and the nut and the bolt provide for manual disconnection of the automatic parking brake.
