[TowerTalk] Brake click on HAM IV rotor

[VeeAthreePL]

Looking for suggestion in lowering clicking noise.

My HAM IV rotor is making loud click (bang) every time I press brake 
release and again when braking (stopping). It is so loud that I can hear 
it three houses away. The tower resonates it so much that click, that I 
am afraid to use it during the night. The same is with the winch on my 
TX455 tower. When raising the tower up, the winch clicking noise is loud 
in the middle of late evening. I will replace it with 3000 lbs worm drive 
winch available here for $80.
Any suggestion how I can muffler brake clicking noise of my rotor? Or it 
is time to upgrade to better rotor?
Can I have brake on the HAM IV rotor permanently engaged so I do not have 
to press it every time when turning antenna? Sometime when pressing brake 
release it emits 60Hz hum. Any cure for that?
