Anybody installed DOT braided brake lines? |
|
|
I'm considering installing DOT brake lines on my 911SC to improve the
braking. I know my car isn't supposed to stop like a Buick when you step on
the brakes, but it does seem to take quite a bit of peddle pressure to haul
the car down, and I'm told this is pretty normal for this car.
Has anybody switched over to the braided brake lines? Notice any
difference?
I just figure since the car is 25 years old it's time to replace them, and
I'm considering the "upgrade."
Thanks.

I haven't done the switch on a Porsche, but I did do it to my 1981
Nissan 280ZX Turbo at about the 18 year mark (and 175K miles).
Subjectively, liked the pedal feel better (seemed firmer) but
objectively I can't say braking distances improved (certainly not
dramatically).
I did this in conjunction with adding Nissan cross-drilled rotors. The
car may not have stopped any better but the rotors looked cool! |

I've got these on my 928. I replace them every year as a safety measure.
They don't improve braking performance. They do improve brake pedal feel
a lot. Really firm and if it's not then there's somehting wrong. Nice to
know at the track.

I installed Stainless braided brake lines on the front of a Honda VF750R and
upgraded to DOT 5 fluid. The brakes felt *stiffer* after the conversion.
Don't know if they helped me stop any quicker. |

I don't think they do. However, the feel does improve dramatically and
if nothing else they are cheaper than a set of stock rubber lines so you
might as well do it. (at least they were cheaper on my 944.)
Take your time when working the lines loose, unless you like breaking
stuff. The old fittings are likely fairly tight and won't come free
without some penetrating oil and maybe even a little heat (as a last
resort.) Don't even try to do this without flare wrenches, and if a
fitting feels tight, clamp some vice grips on your flare wrenches to
keep them from spreading open.
good luck,
nate

We did this on my 86 GTI because the pedal was feeling spongy... solved
the problem although I'm not sure it was any better than using regular
brake lines though.

brake lines though.
From what I remember the braded line was intended for use with real |
race cars that were running silicone based brake fluid which required
higher line pressures. Thus the stainless steel brake web to prevent a
blowout!
A Google search for > "braided brake line" +reason < resulted in the
following at: http://www.mitsubishi-fto.org/workshop/brake_lines/
This article even answers the question about, "why never use old brake
fluid."
-----------
"What are the different types of brake fluid?
The three main types of brake fluid now available are DOT3, DOT4 and
DOT5. DOT3 and DOT4 are glycol-based fluids, and DOT5 is silicon-based.
The main difference is that DOT3 and DOT4 absorb water, while DOT5 doesn't.
One of the important characteristics of brake fluid is its boiling
point. Hydraulic systems rely on an incompressible fluid to transmit
force. Liquids are generally incompressible while gases are
compressible. If the brake fluid boils (becomes a gas), it will lose
most of its ability to transmit force. This may partially or completely
disable the brakes. To make matters worse, the only time you are likely
to boil your brake fluid is during a period of prolonged braking, such a
drive down a mountain -- certainly not the best time for brake failure!
As a DOT3 or DOT4 brake fluid absorbs water, its boiling point
decreases. It can absorb water from the air, which is why you should
avoid opening your car's brake fluid reservoir. For the same reason, you
should always keep containers of brake fluid tightly sealed.
DOT5 fluid does not absorb water. This means the boiling point will
remain relatively stable, but it also means that any water that does get
into your brake system will tend to form pure water pockets, which could
cause brake corrosion.
Two other important things about brake fluid: DOT3 and DOT4 eat paint,
so don't spill it on your car. Also, none of the different types of
brake fluid should be mixed. They can react badly with each other and
corrode your brake system. "

One good thing to do is to get some Permatex brake lubricant and use it
on the hydraulic fittings, so they will not "freeze" (corrode) together,
I am currently restoring the suspension, etc. on my '67 911S and have
found some lines frozen together. I only had to make one up from
scratch, however. I wire brushed the lines and cleaned them with lacquer
thinner, then primed with 2-part epoxy primer, then silver DuPont Imron,
all applied wit? an airbrush. I must say, the lines are spectacular when
reinstalled.
Anything that can come off the car has been sandblasted, cleaned, primed
as above, then painted with Imron. |

Another option would be to replace them all with stainless, your home
flaring tools may not do stainless but you can send your lines to a
company like Classic Tube and they will make you new ones to match. I
bought a rear axle set for them for my Studebaker (unfortunately they
did not have the patterns for the rest of the car) and it is very nice
indeed.

Thanks, Jim. I was wondering if my connection was really dead. I
didn't write the article it was quoted from a Web Page that was pretty
"official". http://www.mitsubishi-fto.org/workshop/brake_lines/
Seems at least someone would have at least said "thanks, that's
interesting" by now. :-(

Not on a porsche but did wonders for my Mustang. When I saw crackes in
the rubber ones I did it as an upgrade/upkeep and would highly
recommend for agressive driving.

Two points. |
1)You forgot DOT5.1 (also called Super Dot4)
2Dot 3,4,5.1(super 4) are all mixable, but best not, as you might as
well flush. Dot 5.1 is not related to Dot5, but instead is a progession
of Dot4 hence the sometimes used Super Dot4).
