Each brake rotor has the minimum thickness marked on the rotor. Keep in mind also that the comparative thickness of each side of a vented rotor must be considered. Even if the overall thickness is greater than the minimum, each side must be within .040" (1mm) of the other.

Try diconnecting the battery for a minute or so, then reconnect it. the computer should reset itself, and hopefully the light will go out.

* All brake rotors have a discard dimension cast into them. Replace any rotor that does not meet this Specification. After refinishing the rotor, replace any rotor that does not meet the minimum or discard thickness specifications.

this is a problem that happens alot you have to use an impact driver for this and a impact torx bit. the driver is a cylinder shaped tool with a 3/8 drive head. you get the impact torx the the impact driver and a hammer. the tool is inexpensive and will do the trick.

Call your local parts supply store or dealership. They will have the information you need.
SOURCE: What is the minimum rear brake rotor thickness for
.331 (In thousandths of an inch) If brake rotor measures at or under this
specification, it must be discarded.That's if you have the V6 and 2WD. IF that's not what you have check here

If that doesn't work got to the autozone website and click repair info then click specification, then brakes and then minimal maching.
