The paper deals with the processes that occur when the hydraulic fluid flows in the channels of the hydraulic block of the brake drive of the open-pit dump truck. The main attention is paid to the phenomenon of cavitation caverns emergence and hydro-mechanical losses depending on the hydraulic fluid parameters and the geometric parameters of hydraulic channels. The SST-HL and SSG turbulence models are presented in this paper. The Rayleigh Plesset cavitation model built into the ANSYS CFX software package is also used.
