I'm still quite new to fixing flats on my MTB--have only done it a couple times. I keep running into this issue: I find it challenging, when putting the rear wheel back on the MTB, to not have any rubbing coming from the disc brake.
The last time, I got so frustrated I took it to my LBS and the guy just sort of magically did it in about 2 seconds in front of me
So today, I just fixed a rear a flat, and I'm following the steps the LBS mechanic showed me(putting weight on the seat to make sure the wheel is in the dropouts correctly for example), and I still find it hit and miss: I have to unlatch and relatch the quick release over and over until I get it to where there isn't a slight rubbing between the pads and the disc.
Finally, I've got it now where it doesn't seem to rub if the bike is perfectly vertical, but if I lean it a hair to the side and rotate the rear wheel I notice a little rubbing (this is when I have it up on one of those little stands that holds it up by the seatstay and chainstay). Not during the entire revolution of the wheel, just intermittently as it rotates. My LBS just performed a tuneup on this bike a few days ago, and I'm confident it wasn't rubbing prior to my fixing this flat, so I assume the brakes are otherwise OK.
Is there any special trick to getting that back wheel on and not having to struggle with the rear brake like this?
Also, I understand it's bad to flip a bike with hydraulic brakes upside down. Well, I did that briefly today during my rather clumsy tire changing escapade. Aside from the slight rubbing I describe above, the brakes certainly seem to be working fine, so is it safe to assume I didn't do any damage flipping it over?
