1993 Chevy Truck Brake Calipers Fail to Completely Release

I have a 1993 Chevy Short Bed Sport Truck, 150,000 miles with 5.7 Liter V8 engine. I have what I think is a strange problem. Anytime the weather temperature seems to get above 80 degrees or so, the brake calipers do not want to work right. It's like driving down the road with the brakes on, the hotter the temperature the more they fail. The brake calipers act like they do not want to disengage completely and they grab the rotor. I've tried replacing the calipers, the brakes lines to the calipers, the master cylinder and the ABS module mounted by the master cylinder. I keep getting told different things to try and nothing seems to work.
Thanks

I had the same thing with my 92 1500 after replacing damaged disc and pads and flushing the fluid it turned out the brake hose was bad it was allowing the brake fluid togo to the caliper but not return when I let off the brakes.(Colapsing) replacing the hose and flushing the bake system to remove the small particales of the hose cleared up my brakes, also remove the fuid from the master cylinder and wipe it out to remove sediment as this may also be a contribiting factor
