Checking Brake Rotor Thickness...
So I know in the manual it says to use this caliper like tool to check the width of your rotors and determine whether it is still in spec or not. For those of us who are not as lucky to have such special tools, is there another way to go about measuring this accurately?
Just wondering what most of you do to check your rotor thickness.

I just run my fingers along the edge of the rotor. If it feels like it's starting to "lip" a little meaning there is excessive wear, it's time to change it out. Stock rotors should last a good amount of miles if you don't track it. Remember to wipe the rotor after you touch it though.

You can also take your rotor to any shop (pep boys, auto zone, local mechanic shop, etc) that turns/resurfaces rotors and they will have the tool to measure the thickness. These shops measure the thickness to be a certain allowable thickness before they can turn any rotor before it is considered too thin and unsafe.

The Mic used to measure calipers has a point on both Anvils in order to precisely measure the width at hair width locations-----I use a standard Mic with a flat anvil to give me a pretty good Ball Park figure.
Auto supplys love to sell rotors and will many times lie or exagerate the wear. And they have you by the *** cuz they know your brakes are down and they whine about "Its Not our fault, thats the Law" when in reality, they could get you one more turn.
Get used to taking your own measurements

A Rotor Mic has points on the anvils, but I dont use one because that is all they are good for....Measuring Rotors where as a standard flat anvil will mic anything with in its range, In this case 0-1" or 0-25 mm.
I believe, with out getting into Digital read out, one can be had for 80.00-100.00 or so. Is it worth it ???

Notice how the measuring surfaces are flat---Im sure Mitu has one, thats for Rotors and those surfaces are pointed
