A device for drawing pressure into two main brake cylinders in the braking system with the pressure equalizing function between the brake circuits comprising from two hydraulic cylinders (1P) and (1L) interconnected by console (6) and linked by connecting tubes (10), comprising a pressure equalizer located in the transverse bore of the cylinder (1L) respectively (1P), which consists of parts - the lower ball (17), a pin (18) and an upper ball (19). Power driven cylinders by this solution allows simultaneous braking the right and left rear wheel and for types of tractors where front axle is braked at the same time braking the right and left front wheel i.e. all drive wheel. Equalizing functionality is effective for both front and rear brakes as well. When brake pedals are disconnected the tractor brake design allows breaking only one rear wheel and the other brake circuits are free of pressure, including the front brake circuit. |
