2000 M2 and I can't get the bolts loose for the rear rotor. It's a countersunk metric allen screw. I didn't mess with them too much in fear of stripping the bolts. I sprayed some PB Blaster in from the back side and it is soaking now. Anybody have any suggestions? I don't know about using heat on such a big aluminum rim. I don't mind messing up the powder coat, I am polishing the rim if I ever get the rotor off. Could these possibly be left handed threads? | ||

normal thread, and man can they be a bear to remove -- heat the fastener head (shouldn't damage the whell is you confine the heat to the fasteners) | ||

Try using a small drift punch in the center of the allen head. Don't beat on them, just give them a tap. I was able to get all but one of the bolts out of my front rotor this way. I had to drill the other one out. Once the head popped off and relieved the pressure, the threaded part backed out easily. The original bolts on the 99 front rotor were recessed allen heads, just like the rear rotor. (Message edited by hootowl on December 28, 2006) | ||

a hammer type impact driver is the key.... couple of good raps and its off. | ||

Heat got two of them out real easy. The other two had there heads drilled and were given a quick blow with a chisel to remove the head. Then I put a small drill down them and they pushed out backwards. I think you were right about the pressure/friction of the countersink holding them in place. Once the head was off they backed right out. Funny story, but the sawzall was used to remove the old tire once the rotor was off. Now it's on to hours of sanding/polishing. Thanks for all the help guys. |
