4x4 front brakes minimum rotor thickness?
My book says discard at or under 1.115." The rotor is 1.410" thick. I believe I have the wrong spec. HELP! Thanks.

hey-Hey!!!,
You can go thinner than spec'd IFF you keep the pads from getting too thin. The heat capacity of the rotor will suffer a bit, so if you happen to *NEED* maximum braking capacity it becomes a bit more important. For 99% of service, you just need to keep the pistons from comming too far out of their bore.

I know it's tempting to save a few bucks this way, but, I think your life is worth more than the price of a set of rotors. Please do this job right.
Also, there are thick & thin rotors for these trucks. Use the thick ones. . they will be much less likely to warp. The 1.414 spec is the thick ones. They are listed as fitting Dodge & Chevy duallies among other applications. You may have to drill out the bolt holes to fit single wheel lugs, but it is worth it. I had to do this on mine after much checking with the parts store's suppliers to see if the y were the right rotors. (they were listed as being right according to the casting numbers on my old rotors)

For liability reasons, most reputable machinists will only go as thin as is cast into the side of the rotor (the min thickness spec should be there).

Those big Bendix 1-ton calipers were used in factory applications with 1.25" and 1.5" thick rotors.
For that reason, I let the 1.5" thick rotors run well undersize so long as they are wearing evenly. I'm not recommending it, that's just what I do on my own vehicles and I sleep at night just fine.
