Re: [TowerTalk] Hygain Rotator Checkup and Rebuilding

From my understanding, the brake wedge was squared off beginning with 
the Ham-IV and after because the tapered, pointy edge in the ham-m and 
earlier were not as strong (that and the use of a stainless steel ring 
gear is the only difference between the "M" and the "IV.").  The square 
edge has more holding power and so that is one reason why the Ham-IV 
has a high wind rating than the Ham-M.  So I'd be careful about filing 
down the wedge.

I would say just make sure you clean the inside of the housing where 
the break engages.  You might also want to lubricate the brake 
mechanism and make sure it slides freely.
