I give up (hayes Brakes)

Dean A. Stepper

I am so tried of my rear brake (Hayes HFX with a 6 inches rotor) squealing
like a stuck pig. Problem is when it is hot it will not be quite. Been
living with this intermittent problem since I bought my Turner 5-spot over
one-year ago. I have tried all the suggestions gleamed from this group, to
no avail. Did not have this problem on my old bike with cheap 525 Hydraulic
Shimano Deores.

I am ready to try another brakes and open to suggestions. The first brake
set that comes to mind is Avid Juicy Seven's.

Well, I can't blame you... disc brakes can be very frustrating. I had to
buy a different brand, I wouldn't look any farther than the mono's

Never tried them, but they sure are purdy!

Those are purdy. Hope makes some nice looking stuff. I would like some of
those 'Gothic' rotors. Hey, ya never know, I could get stranded in the
woods, and can use them to cut firewood.

Have not tried Cool Stop pads...would like to try them, where do they sell
them?

So far no luck at local stores or on line stores will have to call one of
the stores listed on Kool Stop's web site.

Personally, I have had phenomenal luck with EBC pads, but I would have
to agree that the stock pads (on any system I have tried) are no match
for the aftermarket.

Dean, have you tried blue goo?

I use regular grease on the backs of my pads. Less squeal, no probs!

I have not had luck with EBC Green. What is Blue Goo? That is a new one to
me.

I haven't tried the gold, just the green. They stop better than the
Hayes pads, run quiter, and love you long time.

Blue goo is sold under many brand names at auto parts shops, but as far
as I can tell it is all the same. Look for it under "disc brake
anti-squeal compound" and you will find it. Use it on the hub surface
that mates against the back of the rotor, not on the back of the pads.

I hope it works for you. My experience with disc brakes has been that
howls are typically hub issues. If you changed hubs, the noise would
most likely vanish. However, since that is not often feasible, the blue
goo usually does the job.

??? The disc brake pads are what are causing the high-frequency vibrations,
not the rotor itself. The rotor is solidly anchored to the hub, and any
grease you might put between the rotor and the hub would not help with
anything. The pads, however, often just sit on top of (next to) the
pistons, so greasing that side helps dampen the vibrations.

Disc brakes on cars have the blue goo on the rear of the PAD and not the
rotor to prevent squealing. Greasing the rear of the pads on the MTB has
worked well for me.

It is the friction of the pads on the rotor grabbing and letting go,
grabbing and letting go in an extremely rapid cycle that causes the
howl. The rotor vibrating is what you hear, but both the pad and the
rotor together are what create the noise. Some hubs by their nature
propogate the noises better than others, but if a layer of some
vibration-deadening material abuts the rotor it won't vibrate quite so much.
The theory with cars and blue goo on the back of the pad is that the
rotor is a huge, heavy piece of stuff and it is simply easier to place
the vibration-damping material on the smaller, more accessible side of
things. On bicycles, though, the contact area between the pad and the
piston is tiny- not generally enough to do the job.
I am quite surprised that you haven't suffered severe consequences of
your greased up brake pads. It seems to me that those little things get
mighty hot, and melted grease has a habit of flowing, perhaps to places
you really wouldn't want it to. It'd never have occurred to me to use
grease in this application, but I guess if it has worked for you, then
maybe I'm too much of an alarmist. Still, I wouldn't do it.
