My '94 Accord has the same brake clicking sound after braking in reverse then braking when moving forward for the first time. The dealer and a couple of Honda mechanics have told me this is normal. (It's more of a "click" than a loud "clunk" or "clank.")

I also had a clunking" or "clanking" sound from the front end once when driving, especially noticeable when turning and braking. I don't remember exactly, but I believe this turned out to be a bolt on one of the front lower arms that was not completely tight.
