Checking Rear Rotor's? I have a slight pulsation in my car the front roto's are almost new, but they are cheap AZ rotor is there a way to check if it from the front or the back. I know the old petal vs steering wheel and to tell you the truth it feel's like both. and advice would be great.
You would need a dial indicator with a flexible base attachment and a micrometer.
You can measure rotor runout with the dial indicator to see if its excessive. Then check if the rotor is out of parallel by using the micrometer to measure it at 12 different spots.
Most people would not have these tools though, so you would probably have to pull the rotors off and have a machine shop check them.

As far as parallelism, it shouldn't be any more than .001.
