Ran a dial indicator on my '08 Panel LT front brake rotors last night.

.002" on the LF and .003" on the RF.

Is that enough to cause the dreaded HHR brake rotor shudder?

Car is getting a new set of Michelin tires installed today. FINALLY the O.E. FireRocks are coming off. 40k miles of motoring misery with those PoS tires, GM replaced the first set for no charge. Second set wasn't much better.

I am not sure about the run out.

But, my experience has been that the LCA bushing and/or struts are more likely the cause.

And adjusting the rear shoes! The LCAs were my issue

I THINK hyperv6 mentioned, way back........anything over .003 needs attention.

I seem to recall that thread!
