The invention relates to a proportional pressure brake control valve which comprises a valve body and an asymmetric piston located in the valve body. The Asymmetric piston comprises a cylindrical part and a piston part which is vertically and fixedly connected with the cylindrical part; the piston part comprises a first piston body, a second piston body and a fixed shaft which is fixedly connected between the first piston body and the second piston body; a first oil return channel is formed between the firs piston body and the inner wall of the valve body, and a second oil return channel is formed between the second piston body and the inner wall of the valve body; the first oil return channel is communicated with a first chamber formed by the valve body and the first piston body, and the second oil return channel is communicated with a second chamber formed by the valve body and the second piston body. With the adoption of the proportional pressure brake control valve, output force of a driving mechanism can be reduced, and the size and the weight of the driving mechanism are reduced accordingly.
