A vehicle braking system includes a piston rod extendable from an air brake chamber, a rotatable cam shaft, and a slack adjuster coupled to the piston rod and the cam shaft. The slack adjuster is configured to rotate the cam shaft as the piston rod extends. The slack adjuster has a control gear coupled to the cam shaft such that the control gear rotates as the cam shaft is rotated. A pinion gear meshes with the control gear such that the pinion gear rotates as the control gear rotates, and a take-off gear meshes with the pinion gear such that the take-off gear rotates as the control gear rotates. A magnet coupled to the take-off gear is configured to rotate as the take-off gear rotates. A sensor is configured to sense rotation of the magnet, and an indicator is configured to indicate brake stroke of the piston rod.
