The invention discloses a whole-vehicle braking system of an electric tractor. The system is characterized by comprising a suspension foot braking device, a driving steering whole-wheel braking device, a whole-vehicle braking synchronous linkage system, a braking pipeline with a damping structure, a steering flexible connection structure and a reverse connection braking current feedback system. The suspension foot braking device comprises a foot brake assembly and a vacuum booster, and the driving steering whole-wheel braking device comprises two steering wheel brakes and two driving wheel brakes. The whole-vehicle braking synchronous linkage system comprises a six-way valve, a braking air pipe I, a braking air pipe II, a herringbone three-way connector, a braking air pipe III, more than two electric vacuum pumps and a vacuum tank assembly; the braking air pipe I is connected with a vacuum booster, the six-way valve is connected with a braking pipeline with a damping structure, and braking pressures of front and rear wheels are distributed according to a set power proportion. Driving steering all-wheel braking is achieved by operating the foot braking suspension device, and the braking safety requirement under the light weight condition is met.
