and yes I do do have an adjustable brake valve
I'm assuming you are using a DUAL-brake, front/rear system.
So, in which line did you install it the adjustable valve, and where?
On a MOPAR Dual M/C, the front brakes have to run directly to the REAR reservoir on the M/C with NO pressure modifications and no hold-off valves. Thru the Distribution block is fine, BUT, the M/C line comes in on the END, and then splits. In a MOPAR system the lines from the M/C are coded by size and only fit the appropriately coded valve but one way.
Mopar has used at least three different types of valves that I know of, so knowing which one you have is kindof important. The kinds are; a simple distribution block, a combination distribution front with a straight out rear valve, and the same valve with a proportioning valve tacked into the back. This type usually has a safety switch incorporated into it.
This safety switch is supposed to be self centering. But I have seen cases where it it has shifted to one end or the other. When this happens, whatever side the shuttle has moved to, that side of the brake system fails to work, by design.
If you have this type of valve, you can check the position of the shuttle valve by checking the continuity thru the switch to the brass body. In centered position there should NOT be continuity. If there is continuity, it can only be that the shuttle is not in neutral. But you don't know which way it has gone.
In your case, it seems to have shut off the fronts. The only way to move it is to open the rear line and slowly press the pedal until no more continuity is found, then close the leak.
I mean, I'm guessing, right.
Other notes;
>If you do not have a MOPAR valve, then IDK how other brands work.
>If you have clamped the rubber soft-lines, they may have been damaged beyond use.
>If you do NOT have a high and hard pedal, then you have a problem, and
it may not be hydraulic
Hope that helps
