So I'm preparing for this weekend when I am going to (try) to install all new rotors, calipers, pads and all the seals in the front from the axle seal all the way out to the drive member gaskets. That's $300 in seals alone. OOoof.

Anyhoo, I am rounding up all my parts n stuff and discovered this:



It seems that the bag the rotors were in somehow let in some moisture and left the corroded patches you see here. It is not bad, well, in the sense that you can't really feel any difference in the surface. The tooling lines run pretty much continuously clean through the patches, it's not deep.

I'm just sick about this - they are brand new and it never occurred to me to check the BOTTOMS - I just opened the box, saw what looked like clean rotors and put them on the shelf.

Should I try to sand it off? Scotchbrite? Just put them on and hope for the best?

 

I would not be very concerned about it, it's just surface and the first few times you apply the brakes, it will be gone maybe even the first time.

 

Put them on and drive the thing, dont worry about it.

 

x3 on putting them on and not worrying. I would bet money the corrosion is going to be gone after the first stop from 40MPH.

 

If you got the right kind of pads, they have a built-in cleaning system (commonly known as friction).

 

You can clean them up with some scotch brite if you feel you need to but I would just put them on the first time you brake itll be gone.

 

Just put them on. It will probably wash off when you clean the oil off them when installing..

 

Don't worry about it, it will be gone after 30 minutes of driving.
Who's pads will you be installing? Make sure to use lots of sound deadening material and do a full 2 quart brake flush when done.
