I just did a complete front disc brake job with rebuilt calipers , new rotors, pads, and bearings.

When I bolt on the calipers with the new pads, the outside pads drag on the rotor when I spin it by hand while the rear pads have plenty of space.

After I pack the bearings and put on the rotor it appears that the rear bearing does completely seat all the way back to the butt of the spindle. Also the front castle nut goes on but barely clears the hole for the cotter pin. It seems like either the races are wrong or in the wrong spot or the bearings are too thick. If I could push the rotor back about 2mm I would think that is good.

Bought everything at local NAPA

The rotors come with races pre-installed, These are the bearings I have now (all tapered):

Outer bearing - FAG LM12749 - Bore 21.83mm OD 45.24mm Width 16.67mm
Inner bearing - L68149 - Bore 35mm OD 59.13mm Width 15.875

Any direction would be appreciated

Thanks

You should check the seal
It might be too small to fit the spindle
Do the same with the inner bearing
Make sure it fits over the spindle nice and there are no nicks preventing

Some basic questions:
Are you sure those are the correct bearings?
Does the car have the original spindles?
What engine was the car equipped with?
What brand are the new bearings?
