I have a Gary Fisher 129 with Hayes discs. As brakes go, they are terrific. They are precise, reliable, and weatherproof. They are easily the best brakes I have ever had on a bike. But they are also pretty noisy. I don't mean when they are applied, then they are quiet. But almost from the start they have made sort of a soft scraping sound from time to time, especially on turns. Last weekend I took the pads off and cleaned them carefully with alcohol & a toothbrush.
Things were fine for about 15 miles, but now they make a squeaking sound usually about 10 -15 minutes into my ride. Applying the brakes firmly makes it go away for a few minutes. But so far it returns. This sound is coming from the front wheel. The wheel turns fairly easily, but there is a slight amount of drag on it.
Is this fairly typical for these type brakes? Are there any techniques for eliminating this noise? Or should I just get used to it?

Have you tried backing off on the adjustment so there's a little more play in the lever? -- PeteCresswell
Not yet, but I have tried reseating the front wheel a few times and it made a distinct improvement. It was an obvious alternative which didn't occur to me until after I posted the question.

there should be some form of spring [lightly] holding the pads apart. if it's been damaged bt previous wear or is crudded up with mud, it may not be sufficient to hold the pads fully off the disk. that was my experience anyway.

My Hope front brakes (both bikes) occasionally make this sort of intermittant ringing sound - as if somebody was tapping on a bell.
Must be the caliper or pad lightly tapping the disc, but I haven't got a clue why/how.... And it's only occassionally....
All rotors are warped to some degree, whether it be thousandths of a millimeter or an inch or two... chances are that you can bend yours back slightly to flat. My 8-inch was really easy... my 6-inch not so much.

The Avid (now SRAM) mechanical discs on my trike make this ringing noise when I corner hard. It should be noted that the wheels/hubs are subjected to much higher lateral loadings than those on a bicycle would be under normal circumstances.

Come to think of it, the noise on mine - when it does occur - occurs on a curve going out of my development towards the place I ride...that I take at about 25 mph... -- PeteCresswell

Morningstar makes a rotor truing tool which can be used on the bike or in a truing stand. It is the surest way to get the rotor within the tenth of a mm required to completely eliminate rub. I can"t find a web site for Morningstar, but the tool is available from distributors, or contact them at 760-379-2133

The problem is that your brakes aren't confident enough. Replace Hope brakes with Sure brakes for a big improvement, or Know-it-all brakes if you want them to stop the bike even when you don't want to stop. -- Rick Onanian
