You know, I have always heard this, but more that it could warp a rotor, and I have lately wondered, what's the difference between washing them when hot and say, running through a large puddle, you can't avoid that situation sometimes! Besides, wouldn't going to the car wash be just as bad, you have just driven the car!

you are right, its is somewhat the same thing. going through the car wash is the same thing and not a good idea. but most people dont think about it. hitting a puddle of cold water is almost the same, but you arent spraying cold water directly onto the brakes. im sure some water gets in there but not like taking a hose and spraying it directly in to your wheel well. by the way, i had my pads crack on my mitsu eclipse a few years ago from spraying water directly on to the brakes after driving the car. thats how i know.
