New Pads and Rotors Binding?

I would take the MC off the vehicle and disassemble and clean it.  If the seals and bore look OK, then reassemble and reuse.  If you see damage inside the bore, then get a new MC.    While the MC is off, now is the time to flush all of the lines with compressed air, to push out the old fluid and the crud that is probably floating in it.  I would also give serious consideration to replacing the front calipers and wheel cylinders. 

Yeah, I planned on doing the MC/Booster upgrade (the '96+ XJ dual diaphram I believe?); I suppose that upgrade will be coming much sooner than later now.

I would also consider removing the rear load sensing bias valve and clean that thing as well.

That's also a-whole-nother issue I have to deal with, as some components are missing from it completely.

If one is going out than replace both. 

I suppose I'm not asking my question properly. How can you tell if the hub is messed up? "How do I test for symptoms?" is what I'm asking. Do I just start pulling things apart?

So as I made mention before, when I first reinstalled the new rotors and then the second pair of new brake pads, the wheels were spinning freely and quietly. This was because I hadn't pumped the brakes yet to get the calipers nudged up against pads. Just got done doing the break-in procedure and threw her up on jack stands to see how the wheels rotated. This is resistance occurring, and my paranoia is getting the better of me, so I'm just seeing if this seems normal and adequate:

HEY! That's not proper foot attire for a working garage! 

 

Actually, I'm interested in people's response to your video. .

Actually, when I am working on something where I know I won't be dropping big parts (like instrument panel stuff, or lighting) I often wear sandals in the garage.  Of course, when it's 110* out, sandals are more comfortable than regular shoes.

 

To the OP--the drag you are seeing on the wheels seems normal for a disk brake setup.  The pads always drag slightly on disk brakes, and what I see/hear does not seem abnormal.

 

If there were issues with the hub bearings, those are best detected by removing the wheel and caliper, and turning the hub by hand.  Even better, when possible, is to remove the axle shaft, so as to eliminate any friction/noise from any source except the hub.  A good hub will turn smoothly, with no noise.  It won't "spin" if you give it a good turn, so don't' freak out if it stops quickly after you turn it.
