I have attempted to change the brakes, rotors, and brake caliper on my 1997 hyundai elantra, got the pads, rotors and caliper off, the problem i am having is getting the rotors back on far enough on the axle. I used a gear puller to remove them, now i cannot get them to go back on far enough on the axle, thus not allowing me to get the new caliper back onto the rotors. Can anyone help me?
