Im in the middle of a cobra brake conversion but I cant seem to get my current front rotors off. It doesnt have any retaining washers on the suds, or any other thing i can see that is preventing the rotor to come off. BTW i noticed one the ends of one of the wheel studs is paited yellow and i was wondering what that was. any info you can give me thats not in my haynes book o' wisdom would be great. Thanks
