Brake rotor with .003 runout - will that cause shudder?

[632 Regal]

was the rotor bolted to the hub?

Yes.

Did you check the runout with only the screw holding the rotor to the hub or did you have all the wheel bolts installed and torqued? If only the screw then the rotor can be cocked a little causing the slight runout you measure.... And any rust or debris that gets behind the rotor can cause it to cock slightly ..

At any rate as Winfred said, .003 shouldn't be enough to cause a shudder..

Yes.

Busted! Yes it was with only the screw and not the lug nuts.
