No downside as far as I can see. I use them on caliper and clutch bleed, but not on the ABS pump. I like 'em because I can do the bleed solo with the speed bleeders.Dragonwing said:Dep: I've heard of the Speed Bleeders before, and really haven't paid much attention to them. I just took a look at the website. Assuming that they do even most of what's claimed, the question is: Why isn't everyone using them?? In your experience, do they have any downside? I mean, for $7 (or $15 for stainless) they seem like a no-brainer.
