I just converted over to a disc brake system on my 66 coupe. Everything seems to be working fine except that when i went to test the stopping power of the brakes i couldnt get them to lock up. i guess this could be a good thing in a way but it seems odd that they dont. Also the pads are rubbing slightly on the rotors but i figured that was just because they are new. could all of this be an adjustment/bleeding problem?
