When my 2016 Prius with 46k miles was in for service, the dealer told me the front brake rotors had heavy rust and needed to be replaced. I agreed to the work and had the dealer leave the old rotors and pads for me.
There are rings of rust around the outer edge and inner edge on the front and back of both rotors. They are not raised, they are flush with the rotor.
I’m curious what others think of the state of the rotors. Would I have been better off keeping these on my car instead of having them replaced?
Edit: 3 of 4 pads measured 6mm, 1 of 4 measured 5mm
