what sized conductor wire and how far away are the rotor is the shack...
may be a voltage drop issue - or it could be your mast is not true and
it is seized up - this can occur if a rotor shelf is installed first as
opposed to after the rotor being attached and socked down onto the mast
- also if it is a pipe top top section and that pipe is not true you
could get binding, or if your mast is bowed/bent...none of these would
keep the brake from opening or closing but could spell disaster as far
as rotating. Have you loosened the mast in the rotor to make sure it
will spin freely? If not I would start there.
