Brakes Dragging need help with troubleshooting - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Setup: 1957, hydro boost and master cylinder under the floorboard remote reservoir on firewall, 4 wheel disk brakes, Camaro front rotors/calipers, S10 rear rotors/calipers. No check valves in the braking system, they are not needed.

Problem: Brakes work normally for the first 10 minutes, after that noticeable drag on all brakes. Hot brake smell also. All brake lines are routed away from heat sources. Now all brake rotors are glazed over and pads are severely used, only about 700 miles on these pads and set up.

My initial thought is, the hydro boost unit is leaking by a little and putting pressure on the master cylinder, hence pushing on the pads.

Anyone have any other ideas?
