I am in the process of replacing the front break discs on my 2.0cc 1998 Hyundai Coupé the problem that im having id that there is no Haynes manual to use as a guide, and I can not get them of. I can split them from the main hub but that’s as far as I can go, I still can't get them of. Are they a press fit? And would I have to remove the howl hub to get the discs off..??
