New rear PMB alloy calipers. Now no break pressure Options

[Downerman]

OK, OBVIOUSLY no negative to the calipers. Here's the deal..... removed the 911 rear calipers (well for that matter the entire swing arms) but I just let the brake fluid lines hang and drain into jars. Finally got my swing arms mods done and now putting on the new calipers. Filled the brake resevoir up and had all 4 wheels off the car. Used my handy dandy brake sucker pump and had fluid running to all four bleeders on the rear (2 each for a caliper) and then did the fronts. Had to refill a couple of times because I was pulling some darker fluid until it was clear. Went into the cab and hit the breaks. Nothing.... I mean NADA. Pumped like a 100 times to no avail.

RE-DID the entire process again. NADA and I mean nothing. So, I'm wondering if my master has gone south in this time line?? and why?? Seems the only logical answer at this point. Anyone have any ideas?

By loosening the outlines on the MC and letting it gravity feed you will fill the MC with fluid. I use a pressure bleader and do the same thing starting with the MC and then each of the calipers one at a time until no more air comes out, filling the resevore often. Gravity can be used to slowly blead most of the air and then start pumping. Otherwise your MC is bad!

Ok Jeff, I will try this in the morning. Thanks again. BTW.... born and raised in Stockton. My first Porsche was a 72 914 in 1977. Used to know all those back roads/levee's from Highway 4 to Highway 12. I remember when Discovery Bay was built in the middle of a asparagus field.... dang, starting to sound like my grandfather.
