1. A brake adjuster comprising:
a housing comprising a base and a lever arm extending outward from the base, the lever arm configured to be coupled to a brake actuator push rod; and
a control unit rotatably coupled to the housing, the control unit configured to be coupled to a reference point of a vehicle such that the housing rotates with respect to the control unit as the brake actuator push rod extends outward to apply a brake of the vehicle and retracts to disengage the brake, the control unit further configured to cause adjustment of the brake as the brake actuator push rod retracts,
wherein one of the housing and the control unit comprises a first indicator and a second indicator, and wherein the other of the housing and the control unit comprises a third indicator, wherein the third indicator is adjacent the first indicator when the brake actuator push rod is retracted in a brake disengaged position, and wherein the third indicator is adjacent the second indicator when the brake actuator push rod is extended to a brake over-stroke position,
wherein the one of (i) the first indicator and the second indicator or (ii) the third indicator that is part of the housing does not rotate with respect to the lever arm of the housing.
