Make sure you have the bleed valve on top -- if you get a left caliper on the right side, (or vice versa), it is impossible to get the air out!

Bad brake line will do the same thing.

Make sure you have the reservior FULL....

I vacuum bleed brakes these days with my MitiVac -- works like a charm every time.
