Any Dot 5 users here?
I think its one of those things thats up to the user,I dont use it because its a little more maintanence and expense and my driving style doesnt warrant the added boiling point.I used to work at a brake/suspension shop and we used a pressue type bleeder and that worked very well-you can actually fab up a system cheap.We only used the vaccum/siphon type bleeders to get the fluid to the bleeder screws and/or to get the old fluid out-theres no real pressure so they dont mover fluid/air out fast enough or with enough volume.As often as I need to bleed brakes at home (hardly ever) I just borrow someones leg for a while.
