Third, there is a slight burnt smell coming from the brakes after a drive, which cant be good, lol. I think its because the rotors and pads were just installed, and it was just the brake-parts-cleaner thats being burnt off, but i dont know...
When new brakes are installed and used for the first few times they give off a distinctive odour. Also, anytime the brakes are worked hard (say coming down a mountain) they will give off the same smell. That is perfectly normal. Hopefully what you experienced is not anything more than that.

Hot brakes should smell like hot brakes. If you do smell something more like a burnt smell, you should have it checked out.
