disc brake question
N Grover wrote
thanks all, i'll go over those lists and see what happens but most of those things I have tried. I have deduced that either i have superman hearing or my trek mount is too flexy. Grover, my front Hayes does a very good impression of an angry bee when I'm going at a certain speed, is this the "tinging" sound you refer to? If so, I think it appears to be some sort of resonace related problem. If you tap the rotor on the part that is furthest away from the caliper, e.g. if the caliper sits at 3 o'clock then you can tap it at the 9 o'clock postion you might be able to duplicate that same annoying noise. If so I would be interested in a solution too as I have tried all the caliper centering techniques and none of them work. I have resorted to filing the mounts in order to try and make the caliper angle sit more in-line with the rotor - all to no avail. My second last resort will be to buy a new rotor - my last would be to replace the brake altogether. Oh dear, that didn't seem to have helped you at all. |

I'm not bagging on Hayes, they stop better than anything I've tried and I would still use them over V's (on the average). I just want the "ultimate" brake that won't "ting" as much. I have it too and so does my mates - as far as I know it's like a trademark of Hayes. However it's not all the time just once in a while and it seems to be mostly on the 8" disc on my front wheel. That being said I don't think you can ever get completely rid of the phenomenen regardless of what system you choose - it's simply the price one pays for having a brake system with a thin disc and very little clearence between disc and pads.

news thanks all, i'll go over those lists and see what happens but most of those things I have tried. I have deduced that either i have superman hearing or my trek mount is too flexy. Trek's basically don't come with an IS mount, so you have to screw on (three bolts) a trek IS adaptor (which weighs a ton) and then you have to screw on a hayes adaptor (two more bolts) and then the caliper (two more bolts) which leads to 7 bolts and a big distance between the frame and caliper. belive me i can flex the caliper with my hand without to much problem. the rotor is pretty straight last i checked but the real kicker is that it does not rub sitting down, only when standing up. Up front I have a SID fork and although it also "tings" at times i could probably live with it if that were all because it's not as bad. I'm not bagging on Hayes, they stop better than anything I've tried and I would still use them over V's (on the average). I just want the "ultimate" brake that won't "ting" as much. Fair enough. I sympathize with your problem. I didn't know you had that much baggage involved in putting on discs. By the way, do you already have the old Hayes standard attachment holes on your Trek, the 22mm holes on the _chain_stay? If so, you can eliminate all the adapters by getting an old style Hayes caliper half, if such is available for your model Hayes. My Klein Mantra has this setup and my rear caliper mounts directly to the frame with no adapter, which probably affords a more solid setup, I guess. I don't know if this is worth buying from your point of view, but if it is, it would be a very simple changeover. I think cambriabike.com has lots of Hayes small parts, as do some other online retailers. Might be worth checking for options. Good luck to you. -- Off to ride the mountains, D H Reply to newsgroup.

Oh dear, that didn't seem to have helped you at all. no actually that did help, it think it may be a resonance thing. anyway i am glad to hear that others can sympathize. with all the new brakes comming out next year i hope that one of them will cure this (hope's, avid, xtr). anyway, i'll keep my eyes out for reviews of new models. another option would be mechanical discs. they have a pretty good amount of gap between the pad and rotor....but then again i would be changing cables and they may not offer as much power. |

I have heard that the Avid Juicy will be very adjustable, but other than that don't know much about them, except that they are expensive. they are WONDERFUL. i've ridden the 03XTR's and the hayes mag plus... nothing compares to the juicy's. if you've got the dough, they're worth it. a little portly, but i always figure get the good kit- and lose some weight in the gym -- |
