Located the manual, like mrfixit said, the mast stayed in place, removed the planetary drive, oil leaked out as expected, pulled the drum, immediately found the culprit, both shoe springs were broken, i reworked some springs found at the local parts house with some heat and bending, and reassambled the lift while i wait for the proper springs to arrive. Lift is all back together and working as normal. My pads still had at least 5/16 of friction material on them so no need to change them.

When the correct springs arrive i will replace them, and then do the non-problematic side as well.

here are links to the manuals i found
