ABSTRACT:
For an air-operated disc brake there is provided an internal brake actuator stroke indicator which provides an indication, readily ascertained from outside the brake caliper, of the amount of actuator stroke remaining in a disc brake apparatus before a remaining available actuator stroke limit is reached. In one embodiment, the stroke indicator is a mechanical device, readable through a sight glass in a caliper port, coupled to the brake actuator in a manner which results in rotary motion of the indicator when the brake actuator is displaced through its stroke. Alternatively, the indicator may be a rotary sensor such as an electrical potentiometer coupled to the actuator, where the potentiometer sends an electrical signal indicative of the actuator stroke to an external display, such as a remote actuator stroke display at a vehicle operator's position.
