The present invention relates to a brake system of construction equipment comprising: a brake part for braking construction equipment; a brake operating part for operating the brake part; a brake fluid supply part for supplying brake fluid for operating the brake part; a brake actuating part for moving the brake fluid between the brake part and the brake fluid supply part; a braking force reinforcing part installed to be connected to the brake actuating part; a hydraulic fluid supply part for supplying hydraulic fluid to a transmission installed on the construction equipment; a hydraulic fluid converting part for supplying the hydraulic fluid to the braking force reinforcing part by converting the flow of the hydraulic fluid supplied by the actuating fluid supply part so that the hydraulic fluid can increase the flow rate of the brake fluid supplied to the brake part in the case of braking the construction equipment; and a selective block part for blocking the brake fluid, which moves from the brake actuating part to the brake fluid supply part, while simultaneously passing the brake fluid, which moves from the brake fluid supply part to the brake actuating part, in the case of braking the construction equipment. According to the present invention, the burden of a driver having to operate the brake operating part with a great pressing force can be reduced and the braking force of construction equipment can be improved by reducing the pressing force for operating the brake operating part in the process of braking the construction equipment. |
