looking for the org's input on "vent hose for brakes"
 

I'm thinking of adding a vent hose from the lower grille on both sides to keep the brakes cooler. Any comments from the org.?

short answer - you dont need them

the real question is WHAT FOR?......

I get fade when I drive like an A-hole, but not enough to justify race pads.

get braided brake lines

so its easier to modify your car then install pads?
you sure it isnt for looks?

I only drive like an A-hole 50% of the time. From what I understand race pads don't work well until they get very hot, which means when I'm an A-hole I've got good brakes, when I'm chill my brakes suck, hence the question about running street pads and keeping them cool. And yeah it would look spiffy, but if it is just for looks I can waste plenty of time trimming the interior in Louis Vuitton material.

Yes, waste of time indeed. :laugh:

Yeah, yeah, yeah, gotta waste it somewhere. Plus if your lady was throwing out a sick a$$ purse, that you'd paid a small country's GNP for, you'de salvage the foot and a half of material too!!!

I remember reading a couple of threads on this topic, but for some reason can't find them now. I believe they were in the auto-x section.

What you can do is cut a hole in the dust shield and attach the brake duct to the hole. To make it more affective cut the hole right before the rotor enters the caliper.

how exactly will it prevent brakes from fading?

Than get street performance brake pads, like hawk HP.

Just get some SS brake lines and some new high temp brake fluid, that *should* be enough. :madmofo:

If my woman asked for a Louis Vitton Purse, it would be contingent wholly upon the introduction of one of her dancer friends into the bedroom for an evening. I pray you did the same, and such demands were satisfied. :naughty:

Yeah, I missed this reply of yours. Please enlighten me to this.

When brakes get used hevaily, the fluid heats up. Brake lines are rubber and therefore can shrink or expand, when the fluid is hot, rubber line is hot, so when you press the pedal the line will start to expand and result in a brakde fade feeling. Stainless steel lines do not expand, so pedal feel is constant.

Stainless steel lines DO expand. The teflon inner tube will expand/contract to an extent, but is greatly mitigated by the ss weave surrounding it.

Ya I know, but for simplicity the stainless steel outer skin does not expand. Even if the teflon tube expands, it won't be enough to be felt.

404: Fade never found, and you guys KNOW I use the brakes alot.....I felt no difference with the SS lines, and no longer have them on the fronts...back to stock lines up front. Too lazy to switch out rears...

Fade is all about the pads. Get some quality performance, non-track pads like Hawk HPS and you will have no problems.


As to the brake venting idea: It has been done by a few, primarily those who road race, but there is nothing wrong with doing this in a street application, particularly if you are heavy on the stock brakes. I say go ahead and do it....most people are dogging the idea because they aren't adventurous to do something like that (or creative enough).

Worst case scenario: it doesn't hurt anything
Best case scenario: it keeps the brakes cooler.

Sounds like a win-win to me....

high temp fluid works well but isn't really recommended.
IIRC the dot-3, dot-4 has a different viscosity that burns out the moisture better. I also beleive the dot approved fluid lasts alot longer.


EDIT: If Irish says it's a pad issue and not a fluid issue, then nevermind my last statement.

also, using a good brake fluid with a high boiling point, like ATE Blue, is an effective way to increase hot braking performance - moreso than SS lines. You do need to flush it every couple of years, since the high-performance stuff tends to have a bit higher water absorption rates than some of the "regular" brake fluids.

I use ATE Blue, and give it :doublethu

Not saying SS lines are completely worthless, but they're not worth the price in my experience...

we're leapfrogging here....

I see that.
All's well that ends well

Irish, and anyone else with positive feedback , thanks for the info. I'll let you know how it turns out.

I have been toying with the idea of runing ducts for my brakes also, as under very heavy track braking the brake rotors get extremelly hot. I've cracked plenty of rotors in the past, and I would like to keep my stock brakes as I really do not see a need for anything bigger. SS brake lines to not do anything but improve pedal feel, I personally didn't feel anything from switching to them. I run Hawk HPS pads all around and they do not fade at all... but the rotors turn blue under heavy braking. I might pull out my fog lights and use the holes in the bumper for ducts to the rotors.... I am EXTREMELLY hard on my equipment !

Whenever I have some time to do this I will, and post a few pictures.

Something like this would probably work better....
http://www.raretrick.com/index.asp?c...roductsID=7028 You would just have to figure out how to make them.... :bustrun:

$225. is a lot, vacuum hose (pool/jacuzzi hose) at home depot is only $3. per foot. $36. is better for my budget. One of my mods is a FAPR (female aftermarket parts restrictor[my wife]) :mecry:

anybody have anymore suggestions before I proceed

Well those will not work on a Maxima, so no sense buying them. I was merely suggesting to use the basic design features and find a way of making something to work on the Maxima. I wouldn't spend that much on them even if they did fit. :wall:

+1 for the Hawks. I didn't believe it until I tried them. Actually, truth be told, I bought them from Redline under Irish's nose...






(he let me buy the last set at the shop because mine were shot...)

Irish: did you get a new set yet?

I just need rears, so I'm fine for right now using my OEM (dusty) rears...

told you they'd make a big difference!
