The insufficiency of mechanical links to distribute brake actuation energy has led to the development of the tread brake actuator, a modular system comprising generation of required shoe force, a shoe holder with its reaction link, a slack adjuster maintaining correct shoe clearance irrespective of wheel and shoe wear and a suitable parking brake actuator. Modern bogie and wheel axle designs for higher speeds, better curving performance and more installed tractive power put a variety of demands on the tread brake mounting arrangement. A majority of the tread brake actuator systems are air operated with mechanical force amplification mechanisms but also air over hydraulic or straight hydraulic systems have been developed.
