: What do they make these rotors out of?????

Good grief, yesterday I pulled my tires off my 2001 dually on the drivers side front and rear to check the brakes out (not easy to do when you're walkin around in a cast on your leg) and the rotors look like they're a hundred years old! Weird thing is, there is lots of pad left , but the rotors are completely covered in rust, pitted, big chunks of rust getting ready to flake off... I mean, it doesn't even look like they're getting used but once a year and I drive he thing every day. I know when I take it to get inspected next week, they're gonna look at that and tell me to bring it back when I replace it all :mad: . The rotors just look like absolute hell but the truck braking is fine - no noise, no problems stopping. I would swear the rotors are made out of 1970's chinese steel, you know the stuff that's one step above pot metal? I've had *lots* of vehicles and have never seen anything quite as bad as these on a running vehicle.

Does anyone know what the minmum thickness is on these is spec'd? I just want to check and see if they are worth getting resurfaced. Anyone else seen this on their trucks?

yep ,I just had mine in for other stuff and they asked if my truck had been sitting a long time, the roters were rusty mess, and my brakes sucked

Did you replace everything or were they able to turn 'em down to get a fresh surface?

If you want pretty, put on Power Slot's. I think they coat their's so you won't see rust.

Are you guys in areas where there is snow and road salt?

I just checked mine at 85,000 miles I have about 75% left on pads. The rotors did not have rust on them.....
