Does it feel like the power assist isn't working?

That's what I was thinking...that his power brake booster is somehow not getting enough vacuum (or has bled out the vacuum reservoir) at first start-up. If that's the case, I'd check for vacuum leaks but if it's some internal problem with the booster, that could be tricky to diagnose. It would be interesting to note if the pedal "feels" different upon first application---very hard and unyielding.
It would also be interesting to see if you could "stab" the brake pedal a few times before starting out in the morning, to see if that corrects the problem.
