Abstract：In this paper， a new type of wet hydraulic brake device for engineering vehicles is designed. The piston squeezes the friction lining and the brake lining to achieve the braking effect when it is stationary. When running， hydraulic oil is injected to offset the spring pressure to make the vehicle run. Then for the 5t construction vehicle， the specific parameters of the friction pair are matched and the finite element analysis of the pistons under long-term pressure working conditions has been carried out. The analysis results show that for a 5t construction vehicle， its strength meets the requirements.
