Hi All,
I finally got my bike jacked up for the first time. I've been gearing up to do my own maintenance and followed a lot of the advice I got on here (thanks for that).
In checking if my bearings were ok, I spun the front wheel to check for play. There was no play, but what I did notice kind of shocked me. First off, there is a noise when I spin the wheel, as if it's rubbing against something. Back wheel too, but not as loud.
As well, I notice that when I spin the front wheel, it spins for a portion of the rotation freely, then it seems to slow down as if it's rubbing against something. Then further in the rotation, that friction or whatever it is disappears and the wheel spins freely again.
But always with that sound as if it's rubbing...
I inspected my front tire, and I don't see any unusual wear (assuming I know what I'm looking for).
Any idea what's going on? Maybe nothing, but could someone explain why I'm noticing these things?
Much appreciated!

But that's no way to check wheel bearings anyway. Remove the wheel and rotate the inner bearing races with your finger. You can feal if the bearings are smooth and if you have a mechanics stethoscope listen to them.

Fair enough. Can anyone provide advice to this noob on how to remedy the wheels rubbing against the brake pads?

More important is to be sure you don't have (slightly) warped rotors (which cost somewhat more than pads). Warped rotors will show up when braking, giving you a wiggle.
Spin the wheel and study the rotors (and pads). Is there a wobble in the rotor? Pads rubbing slightly is normal. Are your pads about gone? Or is there irregular wear (like more gone on one side than the other)? Put new pads on if in doubt (and clean your brakes and pistons and grease the pad float pins). If the bike has been sitting and the rotors are rusty or cruddy at the pad contact points, steel wool the rotors and/or ride the bike to clean that contact area up. The slight contact rubbing is normal, but it should be uniform, not catchy or intermittent.

I thought you push/pull from side-to-side to check the bearings while on the bike? Yes, off the bike is best.
Also check that the front axle is in all the way. I would need to find a previous post, but there are some with pictures. I think there is a line on the axle that almost sits flush with the fork, think the left side.
