The rear proportioning valve on my 1983 Interstate is leaking. I have checked the connections, and it's not leaking from there. It's between the valve body and the bracket holding it to the frame. From reading on this and other sites, I'm guessing that the valve is cracked. I was wondering if it's a viable solution to coat the valve with JB weld to seal the crack. If not, would TIG welding it be a better solution? I am unable to find the valve anywhere for under about $100 and I'm hoping for a little less expensive solution.

I would tend to do the JB Steel weld fix.
easy to coat around the valve stem, and let it set for a day at least to be sure it is cured.


I once fixed a '84 Ford six cylinder inline engine's exhaust manifold with JB Weld Steel.


that exhaust manifold kept breaking bolts and getting loose.
I took it off, cleaned all the joints up real good, coated every bolt hole and surface with JB Weld Steel.


put it back together, let it set for two days.
That manifold never, ever, came loose again.

JB weld is not likely to hold against brake pressure no matter how you apply it.

JB might work if it is just a pin hole but I am not even sure it is compatible with brake fluid so I agree with Dave and Ken.

Maybe a retrofit adjust to your liking?

Thank you for the idea. I was looking into that, but knowing very little about proportioning valves, I didn't know if that was a viable alternative. I may go this route instead.

Thank you everyone for the great information.
