The invention belongs to the technical field of coal mine special vehicle braking system control, and particularly relates to a full-hydraulic braking efficiency sequential distribution system of a mining rubber-tyred vehicle. An oil inlet of a brake energy accumulator, an oil inlet of a stop valve and a port P1 and a port P2 of a service brake valve are connected with a hydraulic oil source, an oil return port T of the service brake valve and an oil outlet of the stop valve are jointly connected with an oil inlet of a return oil filter, a working port A1 of the service brake valve is connected with a port P of a brake sequence electromagnetic valve II of a rear axle, a working port A2 of the service brake valve is connected with a port P of a brake sequence electromagnetic valve I of a front axle, the port A of the brake sequence electromagnetic valve I and a port A of the brake sequence electromagnetic valve II are connected with a front brake and a rear axle brake respectively, andthe brake sequence electromagnetic valve I and the brake sequence electromagnetic valve II guide brake pressure of the working ports A1 and A2 of the service brake valve to the port P1 and the port P2of the brake pressure replication valve through internal oil ducts respectively. The phenomenon of hydraulic lag of an original vehicle braking system is eliminated, and the use safety of a vehicle is improved.
