hello. after using hayes for a number of years, it's time to try something else. This time I want a hydraulic disc brake that doesn't make that little "tinging" drag noise (ya know the one I'm talking about?). No matter how hard I had tried the brakes exhibited some amount of rub under various circumstances (ie pedaling while standing). If only I could just ignore it everything would be cool but I can't. So my question is, what brake is best in terms of setup and tolerance between the pad and rotor? For me I think the problem is amplified by that silly Trek disc mount system (a mount that bolts onto a mount == very flexy brake mount).

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.

Sounds like the rotor might be slightly bent. This happens to me occasionally; I live in an area with a lot of sticks which quite often get tossed into my wheels - sometimes hitting and bending he rotor.
My solution is to spin the wheel, look in the caliper and see where it's dragging. Usually a few presses by hand on the high side bends it right back.
If it's not bent but still dragging on one side, what works for me is to loosen the caliper mounts, apply the brake and retighten while holding the brake lever. This tends to center it perfectly.
If it's *still* dragging, your calipers may not be retracting - I suggest you then refer to the service documentation for your brakes.
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.

My v-brakes don't ting, they yowl like what you hear from the brakes on a train that coming to a stop. Really. That is actually the main reason I hate rim brakes and won't go back from discs.
Well i knew that someone would tell me to get rim brakes. I'm wanting these advantages that disc's have to offer (in my mind): 1) I like the all-weather performance 2) I like the consitency of discs as opposed to the vulnerabiliy that v-brakes have to a less than perfect braking surface (ie warped rim). 3) I like the mud clearance of discs
What I'm still hoping for is a disc that will live up to the promise "setup them up and leave them for a season".

Well, you just described exactly what I have normally done with my 99 Hayes hydraulic setup. I finally have had to rebuild pistons on one caliper, but that is a pretty simple job and fair enough to be needed after as many miles as I've put on them. I think you are blaming Hayes for something that is not really Hayes fault. I'll admit to having occasional rubs with my Hayes setup, but these are typically very shortlived, not even lasting out a ride most of the time, and therefore probably due to a bit of grit etc that temporarily found a home on the pad. You mentioned the adapter setup. I don't know exactly what your adapter looks like, but most adapters are pretty stout and should handle the job sufficiently. (However, your seatstays are probably flexing more than you think!) I'm thinking that the real issue _might_ fall in one of these categories: 1. Your adjustment of pad clearance was not wonderful to start with, leaving little room on one side? 2. Your frame is unbelievably flexy OR you carry a lot of mass. :-) 3. You use pads that are extra noisy (as some Hayes pads are.) 4. Your hearing is more sensitive than superman's and your tolerance for "tinging" is as low as my wife's (who has a pretty unhappy case of tinnitis.) I'm not here to offer solutions, by the way. Those cost extra. :-) (And have been offered on here many times before, though I've yet to receive any royalties for even one of my many wonderful suggestions!) ;-) -- Off to ride the mountains, D H Reply to newsgroup.

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 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.
Kind regards

This problem is easily remedied. Go to your local NAPA auto parts store and get "Disc Brake Anti-Squeal Compound". Smear it on the surface on the hub that mates with the rotor, reinstall, and ride happy. The stuff is designed to quell the resonance vibrations that plague you.

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.

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 😉

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.
