With the brake OFF along with the actuator shaft extended to its mechanical Restrict, we might want to regulate the extensive hex nut just to the point in which there was no slack inside the cable method – – no much more, no considerably less. If we then take out the hydraulic tension through the actuator, the spring will extend, and also the piston and shaft will go to the best – – implementing the brake.
