Anyone else have this issue? My gen2 premier will develop a whine and casting distance is cut by at least 30%. This happens every month or so. The fix is cleaning the spool edge and the race that the centrifugal pins rub against and applying a very lite coat of lube. I notice the race has either grooving or the pins are leaving a build up of material on the race. This is really getting annoying. It's the only revo I have with this break system so I'm wondering if anyone else has had this problem. I've always loved the gen2 premiers but this is testing my patience.

You should be able to see or feel if the brake drum is grooved. If not I'd try cleaning with alcohol and polishing with a cotton swab chucked in a Dremel. No sanding. Clean the shoes with alcohol as well. If oiling the drum go very lightly.
