I wouldnt be to worried about cooling, if you are just trying to get the most out of your breaks get good fluid and braided lines.

 

what is the best fluid and where can i get some good prices braided lines there like over 100 arnt they?

 

Im pretty sure there are a few FS in the sponsors section.

About the fluid, id just search what fluid people use in the auto-x forum and see how there experiences with it were.

 

Heres a few things to look at for brake fluid.

thanks alot for your help, has anyone ever hear of goodrigde? brake lines

 

hey man, it's basicly you get the duct, 5x7, 5x5, whatever, dual, single, etc.. then you get duct hose.. you want to get actualy racing duct hose instead of the dry washer stuff at home depot.. the race stuff tends to hold out a lot longer. A lot of companys sell ducts, you can get them from northwest racing for like 18 bucks a pop.



there website is http://www.northwestracing.com now as far as getting air to the back of the rotor.. thats gonna be tricky.. you can run the duct to the back but you want to get it as close to the rotor as you can.. so that your kinda on your own. You could get a 12" round aluminan sheet metal, and then put out the center, and bolt it to the hold air duct, then jb weld a 3" ring to the back, and then the hose can clamp on that.. or a freeflow system where its just point at the back of the rotor.. which won't be nearly as effective as the enlosed system.

I'm going to be doing this mod myself very soon, i'll try to do a write up and post it here for you. Any questions, feel free to shoot me a msg on aim, menkio001.

ohh yea, and fluid,

"Wilwood, EXP 600 Brake Fluid, Tested to 626 degrees F with a wet boiling point of 417 F. These numbers far exceed any DOT specs. Low moisture affinity slows the natural absorption rate of water vapor"

good stuff,

 

You don't need brake ducts for autocross.

 

ATE Superblue works very well as brake fluid too. And before you worry about cooling stuff (which I doubt would be necessary for just autoxing in the first place), get some better brake pads, the Ultimates are sort of sporting, but build up heat fast and consequently fade fast. Look into Cobalt GT-Sports or Hawk HP+ ( http://www.cobaltfriction.com ), Carbotech Panther + or XP8. I'm more of a trackday guy than an autoxer, so my personal pad choice reflects that, but any of those should do better than Ultimates. I'm not sure if the XP8 would require warming up or not, as I haven't tried them out myself, but from what I can tell they're equivalent to GT-Sports, which do fine.

 

Goodridge is good stuff.

 

less heat, longer pad life.. cost what 30 bucks to make a break duct system...

You obviously don't autocross.

 

Dude if you are fading brake in autocross especially with upgradeed pads then you have some serious issues other than cooling.

I dont fade brakes on the track with no duct work, BTW i am not very slow either the car run a low 1:12s at beaver.

To answer your question though i run ATE fluid in my car, with goodrigde line, and cobalt Gt-sports for autocross, with 15/16 master cylinder. My car problem is have to much brake.

 

The Ultimates don't have a real high heat resistance though, keep that in mind. They can be faded with moderate to heavy street use, let alone an autox or track day (ESPECIALLY a track day).

 

Don't forget that brakes need to be somewhat warmed up to function best. So if you sit there and design and install this bad *** cooling system that keeps your brakes cool to the touch AFTER THE RACE, then they won't be working as hard as they could.

I had no fade problems at all with Ultimates at Nelson Ledges and BeaveRun with the stock brake system on my CRX. I have never come close to fading them on the street except while bedding them in. Anyone who has should probably have their license revoked.

 

i was going to do some ducts on my crx but after wmhm @ gingerman and no fade what so ever on carbotech panther+ pads i dont think i'm going to

Maybe you're not using them hard enough
No way would I be able to do a track weekend on Ultimates. As further evidence, at ITR Expo '04 a buddy of mine with stock brakes on an EK hatch completely destroyed a set of Ultimates. Like, to the backing plate destroyed, and they were fresh to begin with. They're just not made with a real high heat coefficient or whatever.

 

I ran ITR Expo '04 with my CRX on Ultimates just fine. My instructor in a '99 Civic Si was also running Ultimates with no problems. Operating range is 100-900*F and critical fade temp is 1000*F. Compare that to the Cobalt GT-Sport which has the same operating range and a critical fade temp of 1050*F. By the specs, they are very similar in terms of fade resistance.

Your friend with stock brakes on an EK hatch probably also had an engine swap too, right? Extra weight + going a lot faster than the car was intended to + stock 9.5" fronts = yeah it's going to eat brakes.

Also, don't forget that all these ppl who buy wheels because they look good, don't consider the weight when purchasing. The heavier the wheel, the more rotational mass there is and that means it is harder to stop.

 

as for the ss brake lines. these are what i have. made in canada. they are really good. fitttings are perfect. cheap but topnotch. goodridge is expensive for me

search ebay for "Stainless Steel Brake Lines"
or EK 96-00 SiR
