Brake Proportioning Valve Rebuild?

[WarStryker13]

I'm curious on this matter as well...

I know mine is the load-sensing version, but I know it's supposed to have a check valve in it for the rear drums and I doubt even that part is functioning.

I now suspect I was incorrect about the rear drum brake check valve being part of the LSPV... But I can confirm, without a doubt, that my LSPV is 100% broken.

I took another look at it and found out that the piston is no longer connected to the lever. The shaft and retaining nut is gone, snapped off right at the rubber boot. So now I'm going to have to search the junkyard for one or find a good used one for sale...

There are new LSPVs available for the L200, and they look exactly like our LSPV, but I don't know if it would even bolt up.

If it's from the same generation of truck, it should be identical. Also cross check Mitusbishi Tritons as well as a reference.
