I don't have a picture, but I'm sure many of you probably know what I'm talking about. I recently got to use (for the first time) one of those hand-pump vacuum-operated thingies that sucks brake fluid out of the caliper, instead of having an "assistant" inside pumping the pedal on command. It seemed to work OK, except for the fact that there was a constant stream of small bubbles (coming from in-between the tube and the nipple it turns out).

At the end of purging each caliper, I still had to put one of my kids (the slowest runner) inside and do the old "down... up.... down..... up...." to make absolutely sure the bubbles were not coming from inside.

My question is, was I just using an el-cheapo model, or do they all do that. I must admit, it DOES turn it into a 1-man job. However, I could never be 100% confident the little bubbles were "nothing to worry about".

Thanks, in advance.
