I am having a tough time getting the rear brake rotors off my 00' g-sr. After removing the caliper, I took the phillips retaining screws out with an impact driver. I inserted the jack screws in rotor, but they just pass through the cut outs in the hub assembly that has the lug nuts in it. I expected the jack screws to pop the rotor right off so I was surprised they didn't hit anything when I screwed them in. Any help would be appreciated. Thanks.
