The Vac-type (eg Mityvac) brake bleeders suck! You can never really get all the air out. Much better to use, either gravity, or a pressure type system (I use Gunson Ezibleed). You simply have air in the system, keep bleeding it, and you will eventually get your pedal back.

: Little history: I have spent the last year rebuilding my engine, suspension and doing a very complete once over on my
: beloved e12. The boster and master cylinder were out of the car for 9 months while the work was getting done. I installed
: the master cylinder/booster, rebuilt the rear calipers and installed SS brake lines. The brake system was bone
: dry.
: I bought one of those handy dandy vacuum pumps for bleeding the brakes (NOTE: This thing is great, no more getting my wife
: help me and it is much easier on the master cylinder, $24.00 from Parts America). I bled the brakes, verified that I had no air in the lines, but
: could not get a firm pedal, an OK pedal but not firm. It was even worse when I started the car and started to pull vacuum on the booster.
: Pedal to the floor, no brakes at all and when the pedal returned, it hit a funny detent spot on the way up??
: Rebled the brakes, no better. I can't pump the pedal up either. I cleaned the garage floor, let the car sit for 2 days,
: no leaks. Pulled the vaccum line from the booster and checked for brake fluid. It was wet in there, but no standing fluid.
: Does the fluid get pulled into the engine??
: I understand the brake line layout for the e12 and if I had a leaky caliper, I should have some brakes.
: Any insight would be great!!!
: I think I have done all the right things, sounds like a master cylinder?
