Hi,
I think there is air in my rear brake lines, but bleeding is a
rediculous pain. I know the proportioning valve on the '84 is not
adjustable, but is there a way to disable it? I know the first ones on
Jeeps there was a button that could be held. I just want a way to keep
normal pressure or lot's of pressure to the rears while bleeding.
Right now I can bleed once and then the rears get closed off.

My main problem is that I have either a leak or air in my lines, but I
can't see a leak and don't seem to lose fluid. If I press my brake
pedal slowly it goes about 3/4 or 7/8 to the floor, but still feels
like a normal pedal. When it does this I get pressure to all 4 wheels,
but probably about half of what I'd call normal pressure. If I push
the pedal more rapidly or fast it will only go half way and feel like a
normal pedal with full pressure, but only the front wheels will have
pressure. I'm hoping it's just air in the rear lines and under lots of
pressure that compressed enough to divert the flow and close off the
rears. If it's something more serious then maybe there's a way I can
make the fronts always have the pressure? Right now I can brake fine
with the mostly depressed pedal, I'm just worried when I go to get the
car inspected they will say it's inappropriate that way.

Thanks for any help,
Chris
