Hi all
I just got my front brake drums for my '57 C back from getting coated in high temp semi black. Previously they had been lightly machined (very little taken off to clean them up) and the shoes arced to the drums etc. Now I go to install my wheel bearing cones, and on one drum they just about push in by hand and rattle around like false teeth in the housing when fully installed, both inner and outer on the one side! Tried other cones to make sure, it's definitely the drum.
Could they have distorted the drum,heating it to put this high temp coating.......please, please, please tell me this hasn't happened, they were perfect drums :-(
