Thanks for the replies. I bought one two to three years ago and had the problem. Then i bought one last year and im still having the problem. I got it from FINE LINES. My rubber hoses were originals i got from a car with low miles that was wrecked in a roll over. I drove the car again and it locked up again. I didnt touch the thing and after about two hours the the brakes came undone. Maybe a slow release or poor spring on the piston? Im getting annoyed as i just want to drive the car without a problem for once!
