stiff brakes after new master cyl. - nevrenufhp - 09-15-2012

I thought for sure I bled them really well. I've done my fair share of mechanicing. I swapped out my old one because it started bleeding down at a stoplight. Put in the new one after the bench bleed, but the pedal is stiff, and it's as hard to push as my 67 F100 with 4 wheel drums. Should I go back to bleeding the whole thing one more time? This is getting tiresome.

Replace the seal between the master cylinder and brake booster. Or it could be a bad brake booster.

That was my next avenue. If I push on it slowly, it acts a lot better.
Thanks kind sirrr
