Disc Brake Question regarding flex and noise.
I have a hardtail with Avid BB7 mechanicals. Just a quick question... If I hold down the rear brake as I'm sitting on the bike and kind of move the bike front to back, despite the rear brake being locked, I hear a flex sound, I guess you could say. It's a pop sound that echos throughout the frame, but I think it originates in with the rotor/pads, perhaps they're getting just enough force to move a hair and that's how it makes a sound, I don't know. Trick is, the front doesn't do this at all. Just wasn't sure if anybody else had noticed the same thing or not. Basic question, but one I'm looking for an answer for at that. Thanks!
