new brakes, now no brakes Options

(IMG:style_emoticons/default/sad.gif) end of a long and frustrating day. . .

spent the afternoon installing new rear calipers from PMB, new rear rotors, and new pads. followed eric's instructions (classic thread) on adjusting the venting clearance (I set it at .004"). Parking brake engagement feels normal. I've pressure bled the system twice now, still little/no pedal.  it feels like there's still air in the system, but I'm not seeing any bubbles the last two times I bled the system. no leaks at the lines, calipers, or bleeder screws either.

the only place I opened the lines was at the rear calipers; I capped them right away to prevent any big loss of fluid. When I finished reconnecting the lines to the new calipers, the brake reservoir was still about 1/2 full.

FWIW, I've rebuilt the rear calipers on this car in the past and have never had this problem before. I'm at a loss as to what to do next (aside from having a beer or two tonight). I'll probably try re-bleeding the system again tomorrow, but would appreciate any ideas in case I'm leaving something out.


Thanks in advance!

I've experience (on other cars) with new calipers is it seems like air bubbles will stick on the inside and not bleed out. You'll have to tap on the calipers a few times and bleed again. Sometimes having to tap on the calipers again to help dislodge the air bubbles.

Thanks, I'll give that a try--have to be careful as those new PMB calipers are pretty!

I'm having the same issue with mine. At first, I did have the calipers on the wrong sides, so the bleeder valves were on the bottom and not the top. Fixed that, but they are still soft. I'll try it too.
