I had unsettling moment last night where I went to brake after hard acceleration and momentarily lost brake boost. I made several unsuccessful attempts to reproduce on the short drive home; but I didn't have a chance to reach full boost as I did when the problem occurred. Is there some way that I could be leaking boost pressure into the brake booster? I've never had to dig into how this works, so may be way off; but appreciate any tips for diagnosing the problem. Although it only happened momentarily, I'm afraid it may occur again when I'm not so lucky.
