I wouldn't spray my rotors with water until they are completely cool, just to be safe.

Ok, this came as a surprise? Just a few stops can build up quite a bit of heat on those things, especially depending on speed travelled during that '5 min. drive'. Also, if you can touch them, they are nowhere near as hot as they can be...a spirited drive home would cause blisters VERY quickly.

also dont spray any water or anything on them until it cools off. that is the number one enemy of rotors....WATER
it causes the groovs on the rotors which causes the judder at highspeeds

Yeah i imediately stopped spraying them when i noticed how hot they were. i'm not used to having four wheel disks.

So this normal for them to be so hot?

i hit like 3 stoplights on my way home, i was just surprised to see how hot they got so fast.

It is - all your car energy was transferred to them. If you drive really hard you can see them glowing at night which means temperature way above 400C.

that statement is not entirely true... if 'all' of the car's energy went to those rotors, they'd practicly disintegrate.

Well a MAJORITY of the forward kinetic energy of your car is turned into heat in the rotors and brake pads. Probably upwards 95% of the energy. The rest of the energy is absorbed in the suspension and steering components. And the rotors don't get up to 400 degrees C, maybe 400 degrees F.

I stand corrected - sort of

. I found the link with useful info about iron temperature based on oxide color:

http://www.calaged.org/ResourceFiles...uster/2257.txt

According to that I've exaggerated the temperature > 100C, rotors don't go higher than 300C.
