The invention discloses a multifunctional integrated hydraulic brake system loop which comprises a hydraulic supply pipeline, a brake branch, a left output pipeline, a right output pipeline, a left load, a right load, an oil return pipeline and a controller. One path is connected with a left load through a left output pipeline, the other path is connected with a right load through a right output pipeline, the brake branch is divided into two paths, namely a first branch and a second branch, the first branch is used for realizing proportional pressure output, and the second branch is used for realizing switching between a zero-leakage pressure maintaining function and a pressure unloading function; a left shuttle valve and a left pressure sensor are arranged on the left output pipeline, and a right shuttle valve and a right pressure sensor are arranged on the right output pipeline. The hydraulic system can linearly output oil pressure proportionally and automatically and manually control reversing of an oil way, is small in leakage of a hydraulic loop, is suitable for occasions with high pressure maintaining requirements, and is small in output hysteresis of the output oil pressure and good in repeatability parameter and linearity index.
