APT-P hydrokinetic braking system - development of the ejector performance to reduce residual drag torque (TM-PBS-010)

Excessive drag levels have been measured in the trailer hydrokinetic (HK) brake both with the APT-P installations and with a proposed APT-S "twin brake" installation. This is thought to be due to a low scavenge rate of fluid from the brake. In order to improve the scavenge rate, different configurations...
