Hi
I've just put the air brake back on my Boss, it works well when you turn the spindle on and off quickly but when you leave the spindle running for a long time it will coast to a stop before the brake even comes on.
I take it this isn't normal.
I think it may have something to do with the spindle contacts as these are sticky, I've had problems with starting the spindle when the machine gets warm so it could posisbly be that.
Any ideas about cleaning the contacts? in situ preferably.
