    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!

    It is possible, but there is NO WAY I would do it. Your wheels have too much backspacing. 72THING has a D60 front with 15x10 rockcrawler steel wheel that almost clear with no grinding. They have 2 1/2" backspacing. Check out the ORD forum (I think) and do a search for that subject. He posted the PN.

    That flat plate that the bolt goes through to hold the caliper on, well half of it needs to go. Keep on grinding but make sure only to grind what is needed and no more. I have the same backspacing on my 15" wheels and it is my daily driver. It does look scary but once you are done you still have more caliper then a stock 10 bolt. Remember 1 ton brakes were designed for towing excessive loads with trucks.

    What about the tension spring? Are you not running any? And if not, do the calipers slap around? I am thinking of selling these rims and getting something else. I would really like to step up to bead locks, but they are out of my budget right now. Who sells a good quality rim with about 3"-3 3/4" backspacing?

    I just used 4 inch backspacing on my D60.....ya....I did alot of grinding, about a 1/4", I coundn`t imagine using more than 4". After gettting the calipers fitted, I wish I used 3 1/2" backspacing......it was a REAL B!TCH getting those wheels to fit!

    You have to keep the spring. I had to grind right down to it but didn't need to actually modify it. Be careful if you do. Also, read <a target="_blank" href=http://www.members.cox.net/russhuffman/grinding/calipers.html>this</a> article I wrote.

    The spring is still in there. The lip on the flat plate is still there too. Just half of the flat part of the plate is gone.

    Yep, that's exactly what I had to do. There are pictures in the article I posted.
