brake bleeding - anyone use a vacuum pump ?

[dickfoster]

I did look at motive products but it only come with one adapter that fits many but not all master cylinders. the other adapters run about $30 each and there are quite a few listed.

They have kits that will do almost anything one the road including the old GM masters. I got one of these but so far have only used the standard. I forgot how much extra it was but it can't have been much because I'm cheap. As I said it's the best, easiest and fastest method I've used so I'm gonna hang on to my pressure bleeder.

I've used a hand operated Mityvac to bleed motorcycle and car brakes and clutches. It works well. I have not felt the need for a one way valve as I bleed from the caliper or slave, below the M/C. An electric vacuum pump might pull too much too fast.

I have, too. Just a tygon line into a container with a little bit of brake fluid in it will work, too, by just leaving the bleed screw slightly cracked. You then pump the pedal. Eliminates need for 2nd person.

the mighty vac will easily pull 30 lbs vac if you had trouble pulling enough vacuum you probably got a leak in your hosing somewhere
