If you dind't like Dave's post, this one will probably really offend you... sorry, I type this more as an illustration for others and not as an offense to you.

I didn't see where you mentioned the low pedal - had you mentioned it, bleeding the system would have been the first thing most of us suggested.
This is what makes helping people so hard, we are not standing next to your car - the only way to diagnose anything as complex as your brakes (or whatever) is to be standing right there. Failing that, we need every symptom, and (not with your post, but many) we REALLY get upset when someone posts: "My top won't go up or down" but they do not mention, for ten posts, that the car just came back from the dealer - who had it three weeks and that the top worked BEFORE it went to the dealer - jeeeeeeeeeezzzzzzzzzzzz.

This problem is even worse on Facebook - we actually, every day, get posts like this:
"My check engine light came on, any ideas?" or "My car wont start, any ideas?"

My answer to them, that I won't post:
Yea, I have an idea, but even I am too polite to tell you what I think NOW.
