I had the same issue, thought it sounded like it was coming from the front, I couldn’t figure out what it was, was rotational & would change pitch or stop when I applied the brakes. Turns out it was the rears, and the rotors are trashed now.
Anybody have any recommendation for brands? And while we’re at it, any recommendation on ceramic vs semi-metallic pads?
I got the drilled and slotted discs from Detroit Axle on EBay. I have about 2k miles on the. And am very happy. They seem to be good quality and I like the drilled and slotted look.
