RE: Checked your Brake Hoses Lately?

["Michael Pederson" <mlped@concentric.net>]

Scott -

For what its worth, at least you got a warning with the OEM lines.  I've
copied part of the Stainless Brake line thread FYI below.  Lost my faith in
the "dual diagonal" concept if, in fact such a thing is supposed to be on
these cars  ("dual diagonal" may be old VW info / feature that I'm
"transposing" onto an Audi memory.)

Subject: Checked your Brake Hoses Lately?

I was bleeding the brakes on my 89 200TQ today, as I noticed the brake
pedal felt a little mushy........I was using a pressure bleeder setup which
was applying ~15psi pressure to the brake reservoir........

After bleeding the rears,  I began bleeding the right front wheel, and
noticed the rubber brake hose was swelling up a little in 2 areas, one was
near the end where it connects to the caliper, the other was at the mid
point where the rubber grommet holds the hose to the strut.....

I could feel the brake fluid under the layer of rubber hose where it was
swelling up......needless to say....I will be replacing the hoses before I
drive the car again....the car has 130k miles.....

Those with high mileage vehicles may want to check your brake hoses while
someone pushes on the brake pedal to apply pressure to the system......

Looks like it was a good thing that I did not attend our local track event
this past weekend with this car....

I probably shouldn't even tell you this, but...
I did have your stuff in the back of my car. I feel . . .  .

Well,  Steve I think I'd rather not wait to find out.  I'm replacing all the
lines and putting them on a two (2) year maintenance schedule.

I'm not the most brake, or for that matter any other mechanically component
savvy guy out there, but the other major surprise / disappointment was what
I "thought" was supposed to be a "dual diagonal" brake safety system on VW /
Audi cars (perhaps this was pre-ABS, or maybe ABS negates this feature.)
Any way I thought you "could" loose power in 1/2 the brake system (i.e.
right front/left rear) but were supposed to stile retain stopping power in
the other half (in this case left front / right rear.)

Don't think that happened.  Maybe someone else on the S-Cars list knows.
BTW, there is a separate "S-Cars" list with much less "volumn" than the
audifans list.  Don't know when you dropped off the old list.

Thanks for the info.   Failures to date:  Fronts 0; Rear lines 4.

Mike:

It was a rear line.  I had a pinhole leak which
occurred instantaneously, 1 minute I had brakes,
the next minute, I didn't.  Hmmm, I wonder what
the correlation is for rear lines.  FYI, I've been
lazy and never got around to changing the other
lines and just got back from a SUmmit Pt. week-end
and they've been fine.

Hope your S4 was fine, nice car!  I'm an Audi-nut
Also . . . .

One of the Porsche list members shared some information off the Porsche list
with the Audi "S" cars re: stainless steel brake line failures.  I saw from
the post you've enjoyed one.  Just out of curiosity, was it a front or rear
line that failed?

I had a rear line fail on my S4 at Second Creek Race Track, and so far of
the 3 other cases on Audi's that I've heard of, the were all rear lines.
