    Question Mechanical Disc Brakes: Flickering sound when braking

    Hi, All

    I have a road bike with Avid BB7 mecahnical disc brakes with Avid's G2 Cleansweep rotors (I also have Tektro Lyra rotors). This is my first time using disc brakes so I don't know what to expect from them quite yet. I've gone over many articles, threads, how-to videos about proper setup and maintenance.

    My brakes seem to make a "flickering" sound when I engage them during high-speeds, especially on down-hills, but it also happens on flats at speeds over 19mph. The sound is rapid but soft, very similar to what you hear when something like a playing card brushes against the spokes. I don't think I'm losing any braking power, nor do I feel any vibration on the bike itself at least not on the levers and handlebar from what I can tell.

    I'm not sure if it's due to the rotor design (maybe heat being trapped and released), or the state of the brake pads, or something else.

    Is this "normal" or something I should be worried about? As I have no baseline for what a "proper working disc brake setup" is like, I can't really tell. My LBS won't be able to check it out until the end of the month.

    I've also heard about other complains about the Avid "turkey gobble." I can definitely say mine doesn't sound anything like that, since it isn't a squeal at all.

    Many disc brakes make unique noises related to the design of the disc. I had an old Suzuki motorcycle that earned herself the nickname "Cricket" because the front brakes, made a soft, cricket-like sound.
