Help - Brake Bleeding gone wrong

[ANDREW FINNEY <afinney@bigplanet.com>]

Can anyone help me out here. I installed new front caliper lines on my
UrQ. I bled the fronts, both w/ no problem. Then I started the official
bleeding. I bled the pressure regulator, no problem. When I went to the
right rear caliper all I get is air. I have been bleeding it now for an
hour w/ a vacuum gun and I still get air. What's going on, the same
thing happens with the left rear. The fronts bleed OK though. I wrapped
the bleeder screws w/ teflon so air leaks w/ the screws aren't the
issue. Any help of the immediate kind would be appreciated. Or give me a
call at (914) 969-8328 to save my rapidly deteriorating weekend.
