That mechanical stab trim brake system was changed to some type of column activated electrical cutout system some time in the later models. The brake release knob on aft pedestal normally used to secure the garbage bag on the 727 and, I guess the 737, was replaced by a switch to override the stab trim cutout system. If the Max still has the latest cutout system they must have made a bypass around it for the MCAS. When I was a 727 plumber we checked the brake, as seen on the video, on first flight of the day. 737 drivers please chime in on whether this system is checked/installed on your aircraft.
