My daughter recently bought a 2002 Alero with 73,000 miles on it. 3 weeks later abs, low trac, and service light popped on but then off. Shortly after the brakes just locked and stayed that way after driving a while. Car cools and it seems fine for about 15 minutes and then is locked up again. I replace one bad caliper that wea leaking on the right front but same problem. Ahh help please?

Is there a possibility someone could have put a little of the wrong fluid in the brake master?

The first step would be to have the ABS codes read and see if that explains anything.

I ran a test. I stepped on the break and then tried to turn the wheel it had much drag then I tried to open the calipers with a screw driver and could not. I cracked the bleeder the wheel spun free and the caliper opened easily. I took off the rubber brake line now I could blow air thru it somewhat but under pressure could one of the inner liners collapse stopping the return of the fluid and not release the caliper?

That depends. Have you already determined that it's only one wheel sticking?
Your question just said brakes dragging. If you have isolated it to one wheel, then yes, the flex hose is very likely the cause. If it's more than one wheel you have to look elsewhere.
