I recently got new ceramic brake pads and rotors on my 2LS 2013 Chevrolet Camaro less than a month ago and I've put less than 500 miles on them. However, recently I've noticed that the rear brake rotors are significantly hotter than the front after driving, just based off of the heat radiating from them. In addition, I can smell a bit of an off smell (can't really describe it) from my vehicle, specifically coming from the rear end. I did a quick test and misted some water on the rear rotors and the water instantly "puffs" and evaporates. With the front rotors the water didn't even make a "puff" noise when misted. This was performed after driving about 20 minutes in normal traffic with 2 - 3 stops along the way (traffic lights, stop signs, etc).
One of the original comments from the brake shop where I had this done was that the brakes had become partially engaged while driving due to the rust on the brake rotors which was a partial source of the need for the replacement. As a result, the factory brake pads had worn down the the point of flaking and the rotors had become severely worn / warped.
I would have assumed that braking, regardless of the drivetrain, applies equal braking to all wheels so the rotors should be equally heated.
Is this normal for a RWD vehicle or should I take it back to the brake shop to have this looked at?
