    Ive been having lots of trouble trying to get decent pressure to the rears... when I bleed them it barely dribbles out. I replaced the MC, which didnt help, and based on responses of people that have had the same problem as me, the problem lies within the proportioning valve. I took it out, and Im thinking of just bypassing it altogeher with some new lines that go straight from the master to the brakes. Has anyone done this? What does everyone think?

    My initial thought was to bypass it all together, the problem I came across was I could not find the correct fitting for the rear output. I went to 8 differen't stores in town and no one had a fitting that would work. Thats when I decided to gut the PV. I sent you a PM describing what I did.

    If you're sending that info out, I'd love a copy too. My rear disc just haven't been what I thought they should be (pedal height wise at least). Found another little issue with mine. Amazing how they SLIP when a seal goes south! /forums/images/graemlins/smile.gif

    I had the same problem.
    I think when there is a loss pressure the combo valve shuts down that side of the line.
    I ended up having to bleed the rear line starting at the combo valve and at each joint in the rear line till I could get fluid to come out the rear bleeders.
