FIELD: transport engineering; excavator-loader with brake hydraulic system. SUBSTANCE: hydraulic booster has hydraulic liquid pressure supply unit, brake master cylinder controlled by brake pedal which serves as primary braking liquid pressure supply source connected with brake liquid tank and communicating with wheel brake mechanisms through intermediate hydraulic cylinder and pressure lines. Additional braking liquid pressure supply source is placed between hydraulic liquid pressure supply unit and intermediate hydraulic cylinder. Additional source includes servo control spool, additional hydraulic cylinder and pressure reducing valve connected through pressure main line to intermediate hydraulic cylinder coupled by hydraulic cylinder rod with spool. Hydraulic cylinder consists of two different diameter cylinders whose piston are coupled by common rod. Piston is provided with spring to return rod in initial position. EFFECT: enhanced reliability of operation. 1 dwg
