The sticky brake wedge has nothing to do with the limit switches.
The brake solenoid does not go through the limit switches.
Only the motor windings go through the limit switches.
When the brake wedge sticks, you can hear it buzzing up on the
tower, but you don't hear the "clack" that it makes when the
brake retracts. It is physically jammed. Relieving the jam
by actuating the turning motor in one direction or the other
is the solution. It's a pain. I've gotta get one of those
Rotor EZ thingies.
