    Thanks for the info!

    I've heard that you can pop out the residual valve on the old master cylinder and that would solve the problem (no need for a new 4-wheel disc master cylinder). Any thoughts????

    Hmm..now that you mention it, I think I've heard that too. I just don't know how to do it...maybe it's threaded into the master cylinder?

    I'd say it's worth a shot! :)

    I believe you can use a sheet metal screw and thread it into the residual valve to pull it from the master cylinder port.

    If you pop the RPV you will still have a M/C with inadequate capacity to feed disc brake calipers properly....

    I found the other posts, they mention no need for compensating the residual pressure issue...

    IF... the dodge unit is the same has the wilwood unit (260-4894) then dodge put an inline 10lb residual pressure valve. I say 'if' only because i can't find a spec sheet for the dodge unit, but the wilwood is HERE and they look identical and all of the dimensions are the same.

    i belive that the residual pressure valve is in the porptioniing valve in a lot of brake systems.
