    Default Haas Trunnion Brake Hissing, Intermittent

    I have a 2015 VF-3SS with a TR-160Y trunnion that was bought new with the machine. The A axis (tilt) brake will occasionally, once every several months, start hissing when the machine starts up for the day. No amount of locking and unlocking will cause it to seat properly. If I take the cover off and actuate it a couple times, it will seat properly, at which point I can put the cover on again and it will be good for another several months. Anyone have any experience like this or have any idea what's going on?

    Thanks!
