Has any work been done to the hydraulic system recently?

One of 2 things is happening. Either the fluid has been contaminated with something oil based and that will damage the whole system or the other possibility is the pushrod does not have sufficient free play to released all the way.

The next time the brake are locks, loosen the bolts that hold the master on and pull it away from the booster about 1/4". If the brakes release, the rod is the problem.
