Hayes Bleeding

[Portable Splat Graphics]

silly question, The "small aluminum fitting" that you got from Hayes, does
it look like a small hose would fit onto one end? If so the other end of
that "small aluminum fitting" would fit on the break bleed screw. I think
that's how'd it go, with out see it

I am trying to bleed my Hayes HFX-9 brakes, but the fitting that came
with the Hayes kit does not fit the master cylinder properly.
Actually, the kit I bought did not include the fitting at all, but
when I called Hayes they mailed me one. It is a small aluminum
fitting, and while it does insert into the hole where the bleed screw
was removed, it does not mate at all -- nothing holds it in place and
there is no seal to keep the fluid in the hose. Am I missing something
here? What keeps the fitting in place normally?

Thanks for any help!

All you need to bleed Hayes brakes is a couple of legths of 1/4" tubing
and a 100cc or so syringe. The tubing fits into the master cylinder
hole and it also fits on the bleed nipple on the caliper. Push fluid in
from the bottom and catch it at the top until there are no air bubbles.

It sounds like he uncrewed the bleed nipple all the way and is not
trying to fit the hose in the hole.

God that above sentence just sounds so wrong!

You have the right part. It just presses into bleed hole on the master,
similar to that piece of **** rubber stopper that is supposed to seal
the whole system afterwards.

<begin rant>
Sorry, I just worked on those things a couple weeks ago for the first
time... Hayes should be forced to recall those brakes
<end rant>

The bleed hole on the master should be pointing straight up while you
bleed, so the alum fitting won't pop off or anything.

Hey guys,

Thanks for the help -- I was able to figure out my problem with the
help of Hayes customer support. My problem was that I had mistaken the
Torx screw at the top of the master cylinder for the bleed valve. I
was unscrewing that screw and then trying to use the aluminum fitting
in the screw's recess. Once I realized where the bleed hole is (under
the plastic "flap), everything worked fine.

In my defense, the bleed I kit I purchased did not come with the
correct bleed fitting, and none of the Hayes directions show a picture
of the location of the bleed hole, which is amazing to me. I have
three different sets of Hayes bleed instructions, none show that
"flap" as the location of the bleed hole.

Also, I agree with Slacker -- that plastic plug is totally cheesy and
unacceptable for such an important component.

Thanks again!

It get's worse, the Hayes instructions to squeeze the little bottle and
keep moving fluid in and out never bleeds the system properly, forcing
it through in one direction with a big syringe does work.

Funny you mention this. The front brake on my DH bike went out on me
one morning. I asked one of the lift employees for shop LBS
recommendation that knows how to work on DH bikes/disc brakes. He
sent me down the road about a mile...

The shop dude looked at me (and the DH bike) and asked, "brakes?" I
replied, "yes." First thing he did was to whip out the syringe. He
had the brakes bled, test riding/doing wheelies in the driveway in
about 15 minutes Kinda made me all tingly inside thinking about
well run shops.

The brakes are now perrrrrfect!!! I'll be picking up a syringe shortly.
