wilwood prop valve issues

Folks,
My proportioning valve is not letting fluid go to the rear brakes. It seemed to be working when i first put it in, but not now. I took it apart but can't be sure if it is working.....I have fluid to the "in" from the master cylinder but the valve seems to be going bad....anyone experience this?

Re: wilwood prop valve issues

The way i solved this problem I plugged one half of the M/C and worked on one end at a time by bleeding the wheels until I had a good pedel and fluid.
I then hooked up the other half and bled that end until I had good pedel and no more air.
Get a good helper and another quart of fluid, you can do it !!

Thanks, but I think having the brake system together for a year with no fluid, dry rotted the inner seal.....I took it apart and it seemed to have issues. Once I blew out the housing and got the seal moving it worked better and I had brakes....however, I am going to get a new prop valve just to ensure things are ok......this is/was annoying....I do appreciate you response though...
