Putting new rotors on 2006 Chevrolet Uplander. Need to know what size torx bit to remove old rotor.

 

This may be a dumb question but are you sure you even need one? I have an '08 and I'd be a little surprised that anyone other than the original owner would have rotors with the torx bolt still installed.

At least my rotors didn't have the torx screws

before you remove it. hit the rotor face near the torx screw. this shock moves the rotor in and takes tension off the screw....which can easily strip if you don't do this.
