    are you hefty mofos getting a lot of noise from your disc brakes?

    I just got my first disc brake mtb ( stumpyEvo29r). Avid fluid Elixers.


    I had no idea they make some much grinding type noise when used for more than a few seconds?

    Is it just my 240 pounds or is somting wong?

    Sound is good ...... it means they are working.

    I have disc brakes on my hybrid bike, sorry cannot recall the make model, and no they don't make any appreciable noise when in use.

    If I recall correctly, there is a break in period and that may be what you are experiencing?

    no.it's not your weight. disc brakes can be a pain in the rear. there may well be a break in period. check your manual or check with your lbs. After that normal period of use they should not squeal but searching your particular model may turn up the fact that they squeal. Some are worse than others in that regard. And some are easier to adjust. I got rid of my Avid BB5's because the BB7's are much easier to adjust both sides of the calipers and that makes a huge difference in being able to dial them in. Getting them grimy or getting some oil or contamination can be a real problem. You'll need to learn how to clean the pads and replace them and adjust them. I find disc brakes to be a real pain compared to road bike brakes. I need them for winter riding but I hate them all the same. The idea that road bikes are starting to show up with disc brakes makes me want to puke.

    Could be they need cleaning. Sometimes you can get a bit of crud in them and they make a racket. If they are wet they can squeal a lot. I took a ride that turned into a very wet ride with a friend who also had disc brakes - I'm a Clyde and he isn't, but both our brakes were squealing away when we stopped.

    The noise can be irritating but they stop a lot better than rim brakes.

    The discs on my new bike took a month to really settle in. Even now they get noisy if it rains or the gods don't favor me on the day. I think its just the nature of the beast. And, in the rain you actually have brakes as compared to not being able to stop. They are a real pain the rear to adjust right, especially the mechanical variety.

    Ditto. Since my last tune up things have been staying aligned pretty well, but there's still the need for an occasional adjustment. And just like a car brake it will occasionally squeal when there's debris or water that gets in there. Nature of the beast indeed.

    Avid discs are notorious for being noisy. MTBR.com has an entire thread devoted to noisy Avid brakes.

    Switching the stock pads to Avid's organic pads will reduce noise.

    I have had the same problem... disc brakes are a plus and a curse... I love BB7's but my new bike came with the Elixers. I am waiting to see how they performed. BB7's are not without issues as well. Right now in the front, the outside pad is not functioning correctly and I get squealing and skipping; neither good. Disc brakes need maintenance and adjustments to work properly. Either learn to do it yourself or make friends with the mechanic at your LBS. Also make sure you feather the brakes going downhill, long, steady pulls then to cause heat build-up and grime melts onto the pads.

    No idea off the top of my head what brand mine are , but they only make a loud noise when they are wet or there is mud or something in there.

    I just remember to clean mine once and a while and they are mostly noise free, and stop my large arse in good order too

    Maybe take it back the LBS , they may not be installed correctly ?

    Yes, they get noisy, especially if they are wet. If you are getting more of a grinding sound, they might need to be adjusted or cleaned.

    On a side note, when I was still getting used to the high pitched squeal of wet disc brakes, the "perfect storm" of loud brakes occurred:

    1) It had just finished raining, the air was dry but the ground was wet and I had been riding for 30 minutes.
    2) I was 230 pounds, on a fat-bike, going downhill, really fast.
    3) A college basketball game had just gotten out and the crowd was walking out of the stadium to their cars; another cyclist was several hundred feet in front of me so the pedestrians had cleared a path for him, allowing me to continue at full speed.
    4) WE WERE IN A TUNNEL.
    5) At the end of the tunnel was the bottom of the hill and a sharp right turn, so I didn't have to break until the last minute, but when I did, I braked hard with both wheels.

    The brakes squealed so loud I thought for a second that a train was coming, and of course there wasn't even any train tracks in the tunnel. I didn't know that disc brakes could be that loud. It seems funny now, but I wouldn't be surprised if it made somebody's ears bleed.
