I bought some new brembo rotors for my truck. do they have to be turned before my mechanic installs them?

 

No, not if they are new.

 

Just have him/her mount them.

 

Don't you have to hit them with some brake cleaner to get rid of the greasy protective coating?

 

you can, i did on mine jsut because i got it more greasy with fingerprints when i replaced mine.....

the brembos i got had a really nice crosshatched finish on them.... look way better than any of the rotors i have ever used before....
