When I use the brakes on my 1997 Chevrolet C2500 350ci 8600gvw truck the rear drums lock up on the truck. Now I have new shoes new springs in the rear as well. Everything is textbook but for some reason the drums are still grabbing and I cannot figure it out. At low speeds stopping the tires will lock up and the drums scream when breaking in my neighborhood. I just replaced both slave cylinders. I drove around for about a week and the breaking was perfect and then it slowly started grabbing again and now they are back to full on grabbing. I am very mechanically minded and can fix just about anything on a truck but this issue has me at a COMPLETE LOSS. Please help

Maybe a proportioning valve problem?

I have thought of that but what specifically should I be looking for to see if the proportioning valve is the part that is bad?

Does it have individual rear wheel sensors? 1 on each rear wheel?
