レーキ制御回路。 A brake that causes a circuit between a forward rotation side and a reverse rotation side of a capacity control cylinder of a variable displacement pump for driving a vehicle to flow to neutralize the variable displacement pump, and releases oil on the brake release side of a brake control cylinder to apply the brake. What is claimed is: 1. A brake control circuit for a hydraulically driven vehicle, characterized in that the hydraulic circuit having a control valve is provided with an accumulating pressure chamber between a throttle interposed in a return circuit of the brake control cylinder and the brake control cylinder.
