Hey all just had some success on a project I've been putting off. Had broken bleeders on both my trailboss 250's. Both front and rear have the same bleeder by the way, 1/4-28 thread, available at any parts house. Anyway I removed the calipers from the machine, started with a 1/8 in. drill bit then went to a 5/32, and they came right out with an easy out no heat no nothin. Boy was there some junky looking fluid in there I recommend flushing alot sooner than I did!
