Hello All,
I have a set of steel wheels that work fine on a truck with drum brakes.
When I put them on the truck with disk brakes, the center hole is too small.
Has anyone ever machined down the center hub on a front brake disk to fit in a smaller center hole?
What little I know about a brake lathe looks like it could be easily done.
I need to get some calipers out to see how much material would have to be removed.
Thanks for the info.

Be aware that, depending on the wheels, caliper clearance may also be a factor.

i would say it depends on how much meat is removed so that proper support for the outer bearing still exists.

Bill, if the center hole on the wheel is a little small
why not machine the center hole out to fit the hub instead.
But, if the wheel is not a disc brake wheel you will have
interference between the wheel and caliper. A disc brake
wheel has more clearance on the back side than a drum brake
wheel because of the clearance needed for the caliper.
Might be a better idea to find some disc brake wheels off
a later model truck or through the aftermarket if you want
to run the innie style caps. TR

When I put front discs on my 56 Ranch Wagon I had to machine down the hub to clear stock wheels. As long as there is plenty of material I'd do it that way.

Re: Maching front disks to fit a smaller center hole.
I machined the bearing snout on the front rotors to allow my wheels to clear. As I remember I took about 3/16" off the outside of the snout, back about 1 1/2". I did this almost 20 years ago and there hasn't been an issue.
I was using an original set of American Torque Thrust wheels, and machining them wasn't at option. The "hub hole" in the Americans was tapered, larger at the mounting surface, so a partial trim on the bearing snout was all that was needed. Clearance for the caliper wasn't an issue.
Good luck.

Just put 15 x 7 Torque Thrusts, (probablty TT II's), on my CS with the '77 suspension/brakes, no hub clearance issues. Wheels cleared the caliper until the stick-on balance weights were applied. They then rubbed. I was able to find some thinner width balance weights and put them as far inboard as possible. Problem gone, but it is extremely tight clearance.
