This item may have been described here before with "roses and sunshine" feedback but, IMO, this tool is a waster of $26.95.
It fit so tight on a like - new bleeder screw that I had to use pliers to remove it. It was also so tight that it ruined it's inner seal after one use. Did it allow me to bleed my rear brakes? Yes, and so would the old piece of hose on top of a 8mm wrench and in to a catch container. Did I put a small ding in my like - new caliper trying to pry it off. Hell yes! Did it go in the garbage after one use? You bet it did!
A bit of overkill for a bike, but I bought one of these and LOVE IT ! You'd be amazed how much easier things can be when you can stick a tube down the hole, plug in the air, and vacuum it out. Makes bleeding brakes or flushing out the braking system an absolute one man breeze...
I got mine cheaper at O'Reilly Auto... but here's the listing at Northern Tool.
