Another page to the beated into the ground topic of 1 ton 15\" wheel grindin I am using 15 x 10 w/ 4 1/8 backspacing on my front 60 and I have grinded the calipers. I cannot get them to quit rubbing. I would have to grind alot of the caliper retainers and the tension springs to get them to go. What has everybody else experienced on this? And also, will the clearance get better or worse as ths pads wear? And what about as the rotor's wear? Thanks in advance to all those that answer this over discussed subject!
