I was going to wash my truck today after school, and right when I was about to start washing it my little brother walked up and asked me to take him to the football game. So I took him and had no problems on the way and was gone no longer than 20 minutes. When I got back, I filled up my bucket with water and went to spray down the front fender with water and the rotors steamed when the water hit them. Is this normal? I know that the brakes get pretty hot when you brake, but I have never had this happen before, and it only happened on the front rotors, not the back. The front still have stock pads because when I went to change them they were still at half life, so I left them on and put wagners on the back, and that was about 8k miles ago. Thanks.

 

I would say it's normal,but you never said how long the truck sat before you sprayed it.
Brake rotors get very hot, as they work off of friction. Front brakes do most of your stopping, so they will be hotter than the rears.

 

What he said... ^^

I have experienced this myself wouldn't worry bout it.

Right after a 30 miles long trip I for some reason, forgot and accidentally touched my rotors trying to look at something and they were REALLY hot, which is normal considering you truck uses friction to stop. And what have we all learned in 6th grade science that comes from friction? Heat

 

This is just me, but I don't wash the truck esp the wheels until it has sat for an hour or two... if you aren't careful you can wreck your wheels. That brake dust is so hot, you can burn it on if your not careful I would imagine

 

I figured it was normal since the front does most of the stopping and you can feel the heat when you are near them if you have been driving. It had only sat for about 5 minutes before I washed it.

 

Be careful with this because I had a set of rotors on a car one time warp because I cooled them too quickly
