i had a problem with this so my tech teacher took a grinder and grinded the bolt down took off the disk grabbed a pair of needle nose plyers and just started unsrewin the rest of the bolt
hi ive done this loads it takes a while but worth it get a 1 inch flat file and just phile the bolt ends this will pop ur rotor off then get a 2mm drill piece and drill into the rest of the bolt thats inside the bub make sure u get it exactly str8 when u get about 3 quaters in tap the outside of the hub sightly with a mallet then drill a little more bit of wd40 and they fall out make sure all the debris is out then ur new ones will go str8 in saves gettin a new hu if u get it ryt
