FIELD: transport. ^ SUBSTANCE: invention relates to automotive industry, particularly, to drives of brakes. Drive comprises first contour device, second contour device, first distributing devices, second distributing devices, device to force fluid and valve to direct forced fluid into first and second contour devices. Contour devices allow forcing fluid unto first and second brakes. Second distributing device are arranged between first distributors and first and second brakes to deactivate first distributors in failure of first or second contour device and to communicate feeder with first or second brakes. Hydraulic valve of wheel brake drive comprises body with first inlet, second inlet, first and second outlets, first and second distributors, first and second pushers. Hydraulic joint is arranged between first and second distributors to make first distributor act on second one and vice versa. Hydraulic valve of wheel brake drive comprises body with first inlet, second inlet, first and second outlets, first and second distributors, first and second pushers. Hydraulic joint is arranged between first and second distributors. Third distributor to communicate with second outlet and fourth outlet to communicate with first inlet are arranged in body to selectively actuate front wheel axle brakes. ^ EFFECT: preservation of active braking at oil leakage. ^ 64 cl, 17 dwg |
