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
