TECH DAY: Brakes/Rotors/Pads (Interested?)
#164
Anyone know how I can get rid of these black streak marks on my rotors? Will these come off eventually? What are these? Brake pad or black brake goo? Rear rotors don't have these.

they are just breaking in. Just give it a few days. The rotors will begin to develop their grooves. oh yeah, I think I left my Butt/knee pad (Porsche 911 seat bottom) over there.
