Patent abstract
A brake maintenance indication system having a first portion determines the brake cylinder pressure and a second portion that is configured to determine the intended brake cylinder pressure based on the difference between the brake pipe pressure and the emergency reservoir pressure. The intended brake cylinder pressure is preferably determined to be 2.5 times of the difference between the brake pipe pressure and the emergency reservoir pressure. In the event of brake cylinder over-pressurization or under-pressurization, an indicator is flagged, thus identifying the presence of a problem with the braking system.
