Vehicle is a '91 300-SEL.
Had a local MB independent shop do a turn-key brake job today. Front and rear rotors were replaced.
I noticed the rear rotors have what I'll call a cross-hatch pattern, something like I've seen inside 4 stroke Japanese motorcycle cylinders. The front rotors had a circular pattern that followed the flow of the rotor.
Is there a reason for the difference between what the front and rear rotors look like?
Thanks for your time.
