From my experience you always need new brake rotors when the pads need to be replaced on most European vehicles like my VW's and BMW as the brake rotors seem to be softer than pads and the rotors wouldn't have enough minimum thickness usually stamped on the disc. But the brake rotors on most Japanese vehicles such as my Honda CR-V the brake rotors can be turned 3~4 times and they still meet the minimum thickness requirement.I had issues with disc turning, from some shops.
After that, I started turning my own discs on the lathe, with a dial indicator.
But it's been a while, since I did that. I thought, that lately everybody just replaces the disc with pad together. I assumed that the discs these days, are thinner and they are not machinable, like in the past.
That is good news. Thanks
