k 3500 brake ?

[lifted crewcab]

I removed my bed from my 86 3500 crewcab to start cleaning the frame and to run new stainless steel fuel and brake lines today. when I was looking at the rear brake setup I cam across this rear brake junction / valve that seems to be controlled by rear suspension movement. I will post a picture as soon as I figure out how to post it. My question is can I eliminate this or is this needed? Also if it's needed can I get this new?

What is it? Some sort of load based proportioning valve

My 86 K30 reg cab has one too....for a little while longer

Can the junction stay and just the linkage to the axle be removed or should the brake line be cut and double flared with some new line?
