Hello all! This is my first post ever on these wonderful forums. To start it off, I am a complete and utter newb when it comes to bikes. I am however willing to learn!

Yesterday, I bought a brand new Schwinn Trailway. It's a 700c hybrid bike that has Promax alloy linear pull brakes and Shimano 21-speed shifters (more info may be found here: http://www.amazon.com/Men-92s-Schwinn-700C-Trail-Hybrid/dp/B000KZ1G7Q).

I have been reading around searching for a solution but am really unsure about what approach to take to fix my bike.

I made a video detailing my problem as best as I could. You can find it here: http://www.youtube.com/watch?v=7pYHXyUdkCg

I have yet to ride it as I discovered that the brakes were not adjusted properly. The Non-drive side (fancy lingo ey? :)) brake caliper arm seems to not be adjusted properly. It hit's the tire when it is applied and does not spring back into a proper resting position. Instead, it just sits there rubbing the tire and wreaking havoc along the way. When the brake is applied, if I hold the drive side brake caliper arm in place, the non-drive side brake caliper arm does spring back into a proper resting position.

I've read about a multitude of problems that it may be but none seem to fit it specifically.

Any help will be greatly appreciated.

Some links I found that I felt pertained to this problem are below:

Again, thank you so much for any help!

Readjust the pad so that the mounting nut is lower and the pad is angled upwards slightly more. Should allow it to release from the rim easier.

Thank you very much sir! It worked like a charm.
