Brakes on my 87 El Camino

[enio45]

Understood - and thinking thru this - im getting more comfortable that i dont have solid rear brakes....so from that perspective - prop valve back may be the issue. Easy enough to pop in 2 new wheel cylinders in the rear and see what happens.

On this topic - i have seen the flexible brake lines collapse on the inside on a variety of cars - is there any rule of thumb when it is wise to change out the flexible lines?

You're going to have to bleed the rears after the wheel cylinder replacement, NOW is the time to change that hose too.
