CUCV Front proportioning valve

[usmc80]

Does anyone know where I can find a front proportioning valve or have any idea what other chevy's models are compatible at the junk yard?

whats it for never heard of a front proportioning valve? brakes?

Other rigs to get one from

Yep its to balance the front and rear breaking force.

I could be wrong, its happened before, but I think almost any 80s square body truck will have this valve for you with the correct fittings.

Take it easy, and good luck,
Christopher

I'd get a new one to be on the safe side, ft brakes are nothing to fool with. 81-87 front proportioning valve $78.88 www.carolinaclassictrucks.com no part#.

Thanks I am slowing realizing the same thing. It appears that they used the same valve for 1/2 ton - 1 ton trucks. Hopefully it works. worst case I wasted $10 at the junk yard
