Brake adjuster with brake stroke indicator

A brake adjuster comprising:

• a housing 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 the housing comprises a first indicator and a second indicator, and wherein 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 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;
• a pinion that is rotatably coupled to the housing and that engages the teeth of the control disc;
• a carrier wheel coupled to the pinion with a torsion spring, the pinion and the carrier wheel being configured to allow limited rotation of the carrier wheel with respect to the pinion, and the carrier wheel further comprising a first clutch surface;
• a control screw comprising a second clutch surface that engages the first clutch surface of the carrier wheel, the control screw further comprising teeth;
• a clutch wheel comprising teeth that engage the teeth of the control screw, the clutch wheel further comprising a third clutch surface;
• a worm screw comprising a fourth clutch surface that is configured to engage the third clutch surface;
• and
• a worm wheel that engages the worm screw and is configured to be coupled with a shaft of the brake.
