    Elixer cr noise

    For our 25th anniversary, my wife bought me the RZ 140 Two. I love the bike, light, fast, plush, climbs like crazy! My only gripe is the Elixer cr brakes. The rear brake makes the same noise my old 64 VWs horn made when the 6 volt battery was running low on charge. You can actually feel the vibration through the whole bike! I love their power and modulation, but the noise is hard to take. Ive cleaned and adjusted. The noise started right away, and it has a couple of hundred miles on it now. Any ideas or help would be appreciated.

    I have heard that some people have found adjusting and tighting the caliper bolts help and that sanding the edge of the rotors help

    Welcome to the world of Avid.

    I have the same brakes and hate them. Yes, power. looks. lever feel. But the dam% noise. I clean them alot with brake cleaner, sand them, tighten them, replace the pads, and had them bled. The vibration noise ("turkey gobble") seems to be Avids proprietary technology. Wish I had my XTs back on my preferred ride instead of these POSs.

    Good luck Chicken Leggs, but the turkey will get ya every time.

    I have them on one of my bikes and they are fine, never done the gobble everyone speaks of. I've had avids on most of my bikes and never had that issue, well other than my caffeine 29er with a frame problem.

    I get the same noise on my RZ140. I will eventually replace them with something else. One issue mine had was the calliper was hitting the outer edge of the disc and you could feel it through the bike. I added a washer under the calliper to raise them a little. I still get other noises though.

    dont you just loosen the bolts and squeeze the levers on the breakset and retighten the caliper bolts to make adjustment to get the rubbing of calipers to go away?

    I am talking about the outer top edge as if the calliper is sitting to far down the disc.

    Wow, I was hoping for some good news! Has anyone tried a different disc? Mine does not hit the outer edge though.

    The Avid's I owned were the same way at times. I messed with the a lot. Sometimes I got noise, and sometimes I didn't. I'm not too picky, but I could live without them. My Flash is coming with the Avid CRs also...JOY! Try to sell them on craigslist and get something else.

    This is how I fixed the problem for my Elixir CR.

    Used Motul DOT 5.1 brake fuild.
    Replaced the fluid in the entire system.
    Bled the brakes, took my time, made sure no bubbles.
    Placed a business card between the pads and the disc, adjusted then tightened the bolts.
    Also used Avid organic pads.

    No more noise, and love the brakes.

    I just purchased a Flash 29er, and always bleed the brakes as part of my mechanical check list.
    There was a lot of air in the system, and the bike is brand new.
    I think Avid must have some horrible QC, all three bikes I bought in the past week have had air in the system.

    I just put in Avid Organic Pads and used a Shimano caliper mount adapter (different shape, but some critical measurements as the Avid) and that made them silent. 20 buck fix, not including shipping cost.

    Thanks guys. I ordered some organic pads today. I think Im also going to try a smaller rear rotor, I seem to be dragging my rear tire allot, wearing out my new tire. Hopefully Ill get to try this out in Park City this weekend.
