There are tolerances for the thickness of discs, so long as you adhere to these it is ok to either turn or grind the disc.

There is an underlying flaw with this process (excluding minimum thickness requirements). By not installing the hub mounting surface perfectly perpendicular to the rotating axis of the lathe, there will be brake pedal pulsation.

One sided turns usually vibrate due to uneven pressure on the flange of the disc, also the inside of the hub should be the mounting point of the rotor , and a rubber anti vibration band should be used to prevent vibration, this would work in a last resort , but not the professional way to do it

There is a reason the brakepads don't go all the way to the edge of the disc, and that is so you can tell it's worn out. Thus you should measure the minimum thickness. Even if the disc still has a couple of millimeters left of wear, it has to be able to make it through the next set of pads without falling below the minimum value. Although breakdiscs are expensive sometimes, they must be replaced. Tires and brakes are still a valuable lifeinsurance.

This is what you do if you can’t buy/afford new ones and they may be fine. If they’re under the limit they may warp at which point the problem will be evidenced by a shimmy when braking. Then there’ll be a trip to the salvage yard and the process will begin again.

A disc has a reference face (not diameter) where it locates on the wheel hub.

I was in the motor trade for over 25 years and replaced many brake discs that had worn to their minimum prescribed thickness, some even thinner. Only recently I replaced the front discs and pads on my brother in laws car, a Ford Focus, because the discs were knackered. Then I replaced all four discs and pads on my brothers BMW. Why?, because they were worn the minimum specified limit Finally I replaced the front discs and pads on my sisters Ford Ka because guess what, they were also worn to the limit. At least I can go to bed and sleep easy, knowing that three members of my family can drive their cars on the public roads and stop safely. It's cheaper and safer to buy new discs than to skim a knackered one.
