Abstract

A brake condition warning system for liquid cooled brakes that includes an indicator showing whether pressure in the cooling liquid passing through the erodable brake members has exceeded an acceptable valve which corresponds to an excessive amount of brake wear. Also, there may be included temperature sensitive means for sensing the temperature of the liquid in the chamber preventing the pressure indication until the cooling liquid has reached a predetermined operating temperature thus preventing false indications of excessive wear due to the viscosity of cold cooling liquid.
