Brakes Sticking

PONTIAC GRAND PRIX

I have a 1997 Pontiac Grand Prix, 90,000 miles, 3.8 supercharged engine, with ABS brakes. My problem is the brakes start sticking after about 10 minutes of driving. The car is still drivable when the brakes are sticking, but the resistance from the brakes becomes very noticeable. The driver front seems to be the one causing the problem. I have taken the driver front caliper off and pushed the piston in and out a few times and this seems to temporarily alleviate the problem, for around 100 miles, but the problem comes back. My driveway is on a slight incline and when I park the car, leave it running, and put it in neutral the car will not roll back. But, if I immediately shut the car off, put it in neutral, and push the brake pedal once or twice the brakes will release and the car will roll back. Do you know what could be causing this? Any help would be appreciated, thanks.

FIRST OF ALL, IF YOU HAVE THE 'PLASTIC TYPE' CALIPER PISTONS, I WOULD REPLACE THEM WITH STEEL ONES. ALSO, IF THERE IS A BRACKET SUPPORTING THE FLEX HOSE, LOOSEN IT WHERE IT CLAMPS THE HOSE, ( ON GM VEHICLES I'VE FOUND THIS TO CAUSE A RESTRICTION, ) THEN BLEED THAT CALIPER. I HOPE THIS WILL HELP YOU.
