Bad KH prop valve

[BubbaCuda]

Does any body no if you can fix a KH prop Valve? I went to bleed my brakes after doing a 74 dart disc conversion on my 65.The front bled fine but when i went to do the rear there was no brake fluid flow. I had fluid at the inlet to the kh valve but when i disconnected the brake line to the rear nothing..i even had my son press on brakes. still nothing,, I removed the spring at the bottom and there was fluid. Should i just install an aftermarket prop valve?

Its not a prop valve its just a distribution block with a pressure switch in it. But aside from that, I had the same problem. Take off the cap, pull out the spring. There's a valve in there, pull it out clean it off really good and get it to move in the bore. That's all that I did and kablam, fluid at the rear axle. good luck.
