Brakes rubbing agiainst rim after hard brake?

I recently changed the tires, so I don't know if I did something that may have caused this.

I haven't had enough time on the road to know if it's affecting anything, but when I spin the wheel and then brake extremely hard, the brake pad will stay "stuck" to the rim. Sometimes squeezing the brakes again will give it some room again, but I'm not sure if that's the best way to do it. I thought it was my wheel alignment, so I tried moving it around, and then the other brake pad sticks to the rim.

These are the old two-piece cantilever style brakes. Have I aligned the wheel wrong when I replaced the tires? I don't remember if it did this before with the old tires, but I'm afraid I might have done something wrong? Or are the brakes just not centered?

BTW, I work with my bike upside down on the saddle, could it be that?

First of all, if it isn't causing drag or squaking, don't worry about it.

Assuming you have the tire aligned correctly (line up the center of the tire to the bolt on the brake assembly); then we might assume that the bolt that secures the brake to the frame could use tightening.

Center the brake pads where they need to be. Then, tighten the nut on the back-side of the frame. Don't make the mistake that some cats do by tightening the round nut that is on the front of the brake assembly. That will only tighten the brakes until they eventually won't cinch or loosen.

The OP has cantilever brakes, and Mikes instructions are for caliper brakes. Cantilever brakes have a little screw sticking out to the side just above the cantilever pivot. This adjusts the centring. Some lubricant at the pivot would also help.
