In Russia this is called a micrometer. And what I wrote is called the hour indicator. http://s017.radikal.ru/i402/1111/8d/58e8b64550f4.jpg

maximum runout 0.04 mm.
I mean money stayer. How much do they normally charge? $$$?
:017: Stop and think for a minute. You're asking someone in Russia what they usually charge for checking rotors in the US. Call your local brake shops or check with your mechanic. You'd already have your answer if you'd done that in the first place.

This is commonly called a dial indicator, it it used to help determine runout, warpage, out-of-roundness, etc.

This is, in fact, a bunch of micrometers, used to measure exact length,width, diameter, etc.
Just wanted to help clarify :)
Translator first put the question on the money. I thought, why do you ask resident of Russia, about how much it costs in the US? And I thought you were asking about microns and curvature. However, the translator was right. I don't know how much it costs in the united states. In Russia the price depends on the made work. For example, if the brake discs sharpen on the lathe, the measurement of parameters is free of charge. Sharpen - 30-40$ I call the approximate price.
