I would assume that the last time you bled the brakes was if/when the dealer did it. I would also suspect that your pads are pretty worn. Plus, beginners tend to be a little harder on the brakes since the tendency is to get on the brakes early and stay on them which creates a lot more heat.
So you probably need to do some maintenance on your brakes - fluid/rotors/pads.
I think recommendations for auto-x pads would be different from track pads. I know my PFC01s need a little heat in them before they consistently bite...not sure if you want that for auto-x.
