F series 515818287 when you try to back up it put a load on the motor like you push the green lock button

Yeah, I'd pull that brake assembly off there and fix it... then pull the plates off the sprockets and see if you can salvage/grind them otherwise more part$

Removed the middle cover plate with the traction lock soleniod on top and found the the bolt that holds the wedge lock bar to the soleniod plunger had broke. Took a magnet and found the broken bolt laying in the bottom. Took care of the problem a $10.00 fix but a few hours of labor. Never found the little washer or the spring.
