Brake quick-release for side-pull?
I love my Schwinn Gateway (Target bike, also called Wayfarer to Schwinn or Kmart, or Admiral in Walmart).
Recently, I've discovered yet another reason why, when I tried to repair a flat tire on a freebie mountain bike.

Zoomie's brakes
Zoomie has V-brakes, or linear pull, where there is a little metal elbow sitting into a bracket. All I have to do is squeeze the brake arms together and the noodle comes out of it's little holder and the brakes open wider to let the wheel come off.

All the other bikes we have now (blue one, Foreman, Chainless, and even the brand new Next Parowan) have side-pull brakes. I can't see an easy way to release them to remove the wheel.
Is there a trick I'm not noticing to them? If not, can I buy something to install to make these brakes easier to deal with? If it's as easy as possible to fix a flat (or anything else that goes wrong), the other people in the household might warm up to riding with me more.
