Biggest problem i had was getting the front discs off the car !! They were seized solid, i even belted them with a large club hammer (on a piece of timber) and that wouldn't do it either. In the end I put a large bolt through the hole that the carrier fits to, and as i put it through i put a nut on it so that the nut was between the carrier and the disc. Then i tightened the nut back against the carrier which in turn pulled the bolt through and up against the disc, eventually the disc popped off.
