The bump when you first turn over the ignition isn't uncommon, it happens in my car. I don't remember how to fix it, but it's pretty simple if you think it's a problem. It won't damage any of your equipment though.

As for the bump when you hit the brakes...uhm...I have no clue, definately check your wiring
