Abstract
A brake chamber stroke indicator system for a brake system including a brake air chamber includes an indicator rod or a string pot gauge including a housing with an indicator rotatably positioned within the housing. A string has a first end attached to the indicator of the string pot gauge. A spring urges the indicator to rotate in a first direction whereby the string is retracted into the housing. The second end of the string is attached to a brake push rod or a pressure plate. The indicator rod is mounted by a base onto a pressure plate.
