When was the last time you got the oil changed? And was it by a shop? Sometimes they will accidentally put a petroleum based product in your master cylinder and then the brakes lock up due to the seals swelling. But then let go after away and then lock right back up. The way to check is to pull some brake fluid out with a syringe and squirt it in to a glass. You will see oil desperate from the brake fluid and it will be a creamy color.
