Another problem I saw with the GZ is the rear brake. On the inside of the brake drum, on the actual wheel there are little fins that look like turbines, what use they serve I do not know, probably cooling. Anyways, on my bike there would be a squeak if I rolled the bike a foot or so, so I stripped the back brake apart and found that one or both of the little springs that hold the brake shoes in place was rubbing on the little fins. It hasnt effected my braking capabilities, but it will get annoying after a while. I have yet to hear my front brake squeak, but before I got new brake pads on the front, there was some constant contact causing a little scraping sound. You might want to replace the pads, their really simple to replace, takes me only around 5 to 10 minutes, plus their not expensive a all.
