TRW's front axle EPB offers improved affordability, requiring only small modifications to the front axle calipers and integrating the necessary electronic components and software into an existing ESC control unit. Similar to conventional rear EPB applications, the front axle system offers simple vehicle assembly within the wheel environment and enhances emergency braking performance through integration with ABS/ESC in the event of hydraulic failure. Front axle EPB systems have the potential to further reduce the cost and weight of the rear drum brake systems which no longer require shoe actuators, linkages, fixing devices, cables, or the handbrake lever itself.
