ブレーキシステム。 a hydraulic brake disposed in the flywheel housing of the diesel engine to apply braking force to the flywheel; and a position detector that detects the easy position of the injection pump below the no-load position when the engine is rotated by a load. A drive circuit that outputs a drive signal in response to a signal from the position detector is connected to an oil path that communicates an oil tank and the hydraulic brake with a discharge side of an oil pump provided in the engine and driven by the engine. An engine brake system comprising: an electromagnetic switching valve that is switched by the drive signal to supply pressure oil discharged from the oil pump to the hydraulic brake.
