Remember, only the later cars (73+, probably some 72s) need to modify the BMW calipers. Early cars should not need that.

L. McChesney, you were precisely describing the power bleeder that SGomes mentioned in his first note.

SGomes, cracking open the output of the P-valve is indeed a good way to get brake fluid all over everything. And brake fluid eats paint. (Slowly.) So you probably want to have a rag loosely wrapped around the fitting when you are opening it up. And make sure to wash down the area with water afterward--water actually dissolves/dilutes brake fluid.

That "brakes stay locked up" problem doesn't sound so good. It could be something as simple as the calipers themselves sticking... Were the BMW calipers rebuilt, or used? Have the rear calipers ever been rebuilt?
