You take your BFH and hit the rotor until the rust is knocked off and the rotor is free. You can hit the hot of the rotor, as said. I also hit the braking part of the rotor, rotate it, and hit again, and repeat. Good thing I live in rust-free New Jersey where I don't have to deal with this ever. __________________ ![](image.php?u=14385&type=sigpic&dateline=1451887347) 2000 M5 -> 1996 318ti -> 1997 328i ![cool](http://www.318ti.org/forum/images/smilies/cool.gif) Instagram: ndrewchow YouTube: MINIzguy |
