Hi, I just have my rear brake rotor replaced with brake pad yesterday. But I found mechanics machined the disc to 0.335" thickness which is the minimum thickness according to Spec (the standard thickness is 0.394"). I just wonder if this is normal procedure to machine a new rotor to minimum specified thickness. If that’s true, does that mean I have to change rotor again when replacing pad next time, because mechanics will not turned the rotor below the minimum thickness.
Thanks for your opinion
