Yes, would love to hear a solution for this everlasting problem. Where do you get the gauge that is referred to that measures the pressure in the brake line. I guess that could tell us if we have a master cylinder that has a bleed off problem at the seal, or if a brake caliper is having a bleed off problem. Let me know about this. A firm pedal, like that on the American made cars and the Japanese imports is what I feel is desirable. My wife has a Subaru and the pedal on that barely moves and the pedal starts getting firm. I had a Chev. HHR until recently and the brake's were great on that car, too! Very nice brake feel!

I solicit any helpful information.
