55.2-59 S10 Brake Proportioning Valve Lines

[Driver_WT]

My AD truck is sitting on a 1993 S10 chassis. I am just starting to plumb the brake lines, there are no brake lines currently on the truck. The 1993 S10 brake proportioning valve has two lines going in the top (input lines from master cylinder) and then two output lines - a 1/4" brake line to the rear brakes and a 3/16" brake line for the front brakes. Based on pics that I have found, I was expecting the brake proportioning valve to have two output lines to the front brakes, but mine has only one. Can I just put a 3/16" tee in the front brake output lines and then run a 3/16" line to each front brake caliper?

Thanks.

Many vehicles built before ABS have a single line to the left front then Tee off to the wheels.

the factory tee is usually on the drivers frame/engine on s10s, so yes, as 1project says, a tee will be fine

on abs equipped trucks there is no tee, just separate left right outputs
