Abstract
A brake system includes a tandem power transmission unit selectively driven by a first electric motor to provide pressurized hydraulic fluid to primary and secondary output lines. A plurality of iso/dump control valve arrangements is provided, with each being associated with a selected wheel brake and selectively provides slip control to the selected wheel brake. A first traction control iso valve is hydraulically interposed between the tandem power transmission unit and at least a selected iso/dump control valve arrangement via the primary output line. A second traction control iso valve is hydraulically interposed between the tandem power transmission unit and at least an other iso/dump control valve arrangement via the secondary output line. A DAP power transmission unit is driven by a second electric motor for selectively providing pressurized hydraulic fluid to the iso/dump control valve arrangement of at least one associated wheel brake.
