I am doing my disc swap on the 14bff. I am using kert's brackets. The problem I am running into is the outside pad is rubbing the rotor, and there is a nice size gap on the other pad. I can barely turn the rotor it is rubbing.

I am just wondering if anyone else has run into this?. When I adjust the bearings I can feel them hit the stops when I slide the rotor on, but to me it feels like the hub/rotor isn't slid on all the way.
 
I assume you made sure the lugnut studs are in all the way ? I have read about the seating of the studs, to make sure they are seated. Some have mentioned about possible grinding the shoulder of the stud head ?
I would start there.
 
Yeah I replaced the studs with the longer ones that seat better. Both sides are doing it, but one side is slightly tighter than the other. I just figured the rotor would align more center of the caliper.

They both turn, it just seems to me that they shouldn't be touching, or at least touching that much. I'll try to get some pics up here.

I know the pics aren't great, but it wouldn't focus and I don't have my SLR to take better ones.

The outer pad it tight against the rotor, and the inner pad has a good size gap. While the caliper is flat up against the caliper bracket so it can't go out any farther.
 
Try swapping brackets to see if the bracket might be off a little. If it is get in touch with Kert and I am sure he will take care of you.
 
I ran into a similar problem using TSM brackets on my SF. I just used thin washers to space it out some.
 
First off are the pistons in the caliper compressed ALL the way in? If not then you would have the issue you're having. Also did you replace any of the bearing races in the hubs? If so and you did not get the inner race seated fully this would also cause your issue.
 
Scott, I did replace all the bearings and races, I pulled it apart and double checked and they felt seated.

The caliper piston is in all the way but that's not the side that is hanging up. There is a pretty good gap between the inner pad and the inside of the rotor face. I don't think shims should be necessary since Kert's brackets are awesome and are bent to eliminate the shims.
 
Have you pushed on the caliper at all from the backside? The caliper "floats" on the mounting pins and could just not be centered properly (this won't matter once you hit the brakes the first time as it will center itself).
 
Yeah it's flat up against the caliper bracket. It barely slid on because of that pad rubbing the rotor but its on there. Both sides were the same, but the rotors do turn, but they shouldn't have that much pressure on the pad from the get-go.

we need more pics from more angles and from a little further away

Or make sure to use the macro mode on your camera. The little "flower" selection if your camera has that feature, nowadays most do. It should allow you to take pics up to a few cm away.
 
This axle is not in a vehicle yet is it? If it was i would suggest hookint the brake lines up and bleeding the system to see what happens. It could easily be that everything just needs to "settle". Looking at the latest pics i think your races are fine. Can you get a perfect direct inline shot from behind the caliper similar to the first pic in the last set (it is probably the angle of that shot but it looks like the caliper bracket isn't parallel to the rotor).
 
The oil/grease seal in the last pic doesn't look seated enough. Shouldn't be much of a gap if any. your looks like an 1/8 gap or so. Also, when I did my swap the rotors took a bit of effort to spin too but when I put the 35" tire and rims on the hub I could spin the entire assembly fairly easy with just a finger or two. Like Scott said check the races or bearings as the seal looks like it has a ways to go.
 
I pulled it all apart. The races are seated all the way, and the seal actually goes on farther than the original one, the groove from the old seal is inside the new one. I put it back together and it rubs. IDK, I guess I could let it ride and wear off some of the outside pad and not worry about it.I don't want to shim anything out. Maybe Kert will chime in later.
 
Call me at the shop. I'll send you a new bracket.

Should be 3/4" offset in the bend itself.
