A friend of mine was parting out a camaro and gave me the rotors which are brand new in thickness (checked with micrometer) but are rusty all around (sitting in a junkyard for a while). Question is can these be machined and cleaned since they look good (no groves) and have the right thickness? are should I just toss them?

Thanks

 

Yes you can turn them and use them, the rust won't hurt anything.

 

If they are brand new than they shouldn't need to be turned. As soon as the pad makes contact with the rotor surface it will get rid of any surface corrosion.

 

yup... if they are new, and just rusty, you dont have to even clean the rust off..

the day after next time it rains, look at cars that have been parked. the rotors will have surface rust on them.... thats because its bare metal...... as soon as the wheel starts turning, the pads will knock all the rust off.


if you want the areas that the pads dont touch to look nice, paint it.

 

okay thanks for the advice...I checked them with my micrometer and they are pretty close to brand new. Is there sometype of solvent I can clean them with at least since there is dirt and crap all over the vents...I knocked them out with a screwdriver (lightly) but would really like to clean it up...what can I use to clean the whole rotor?

Thanks....

 

Some high-speed driving would probably do it.

You could use brake cleaner...

Or- even better... chances are you wouldn't be re-using the bearing races, right? If they're rusted up, you shouldn't use 'em... Anyway, hose the whole damn thing down with straight-up water! When you're done, shake the rotor off (but don't dislocate your shoulders or drop the thing on your foot!), lay the rotor down on newspaper, and spray it with WD-40. The WD-40 will get rid of all the water.

Watch out for spiders... I got rotors out of a junkyard... didn't look at 'em too closely as I took 'em off the car, got them home, flipped them upside down, and almost crapped myself. There was a HUGE dead spider in the inside corner of the rotor, where the rotor would've been facing the engine. (laughs) That wasn't what I was expecting to see, especially a few inches from my face! Those junkyard spiders must take steroids or something...
