The current market trend is to sell fully coated (painted) brake rotors for aesthetic and rust-prevention reasons. During the pad break-in process, theoretically, the pads will remove excess paint from the pad-contact sections of the rotor.
I recently had an e-mail exchange with a product mgr. (not CSR) at a major brake pad manufacturer. The person advised me that their pads are not aggressive enough to fully remove the paint from some coated rotors. As a result, the coating sticks to the friction material and can cause issues. I have personally seen this with a few coated rotors (mostly rears) where the transfer layer will have visible remnants of the silver coating for the first few months.
The person's recommendation was to remove the coating from the rotor surface before install.
Most of these coatings are very resistant to being removed by brake cleaner. Is there a solvent that can remove this coating in an efficient manner?
