Hi all,

I'm wondering if you guys can tell me what the advantages are for using ATE Brake Fluid on our cars?

My car gets to see ~8 track days/year (I'd love to do more if time/money permits me to), do I need to change my brake fluid to ATE?

Thanx in advance

Hi Pin:

Given that the Factory used the same brake fluid (sans the blue dye) in your 993, you can stick with the ATE Type # 200 or Super Blue; same stuff-different colors.

These fluids are known for a very low level of moisture absorption as well as excellent wet & dry boiling points. That low moisture activity helps prevent internal caliper bore and MC corrosion caused by accummulated H20.

Steve has a lot more to say about brake(s) and brake fluid. Check out his web site at the address below for a very comprehensive discussion on brakes.

Hi Steve,

Thanx for your good insight, it helps me to understand more about my little car

Miller, thanx for a great reference too (another credit goes to Steve for that website)

Thanx guys, have a great weekend...

Guys,

When installing brake cooling ducts, where should I direct the air?

From car's side of the disc to the center of the disc/wheel assembly? Straight to the disc? Cylinder?

I don't know about anyone else out there, and maybe I may be ****, but I thoroughly bleed my brakes (ATE Super Blue) before EACH track event I participate in. I can tell you that I'd much rather loose the ability to acclerate than decelerate. Even doing that, I sometimes get a soft pedal with my car (89 930) and am installing a brake cooler kit (Purchased from Steve W.) and will see if I need to upgrade to Big Reds.

Regards,

Edward

Nothing "****" about that. I'd call it prudent behavior tempered with a desire to stay alive!

I am a big believer in these cooling ducts - anything to add air to the rotor has to be a help. I have used the ones that mount under the A-arms; Alan Johnson makes nice ones. Unfortunately, when I was looking they didn't have one for the 993 (believe they do now). The kit I got was for a 964 Turbo. The duct exit is at the back of the rotor face, between the McPherson strut and the steering linkage rod. The exit duct took a little bit of monkeying to make it fit, but it's been in place for about 2 years now without problems.

LOL,.....IMHO, one cannot be too "****" about anything having to do with brakes. I've seen the the results of people cutting corners on that stuff, far too many times.

Hey Petu,

I have a a front brake cooling kit on my car. I should have showed it to you last weekend.
It's a custom job by Foreign Affairs. But it's a pretty simple configuration.
Underneath the car, attached to the belly. I have two air scoops attached to some hoses.
The hoses are zip tied and point onto the inside of the rotors. It's very important to get the hose real close to the rotor though.
I don't have pics from the C2S but I had the same config in my audi S4. I'll post the pics of that. Also, look at this pic of my car at Sebring. If you look at the picture, you will see on the belly of the car I have 4 things that look like screws... Hope this helps..



These are from my Audi..

Suwipin,

My two cents -- don't use Super Blue unless you don't mind having your brake fluid resevoir permanently stained blue. I use (now) ATE Gold all the time. Since I renew the fluid about 3 to 4 times yearly, it's hard to tell old vs. new fluid, but you get used to the right amount coming from each caliper. One bottle of ATE every few months and track weekends keeps the fades away!

I got some ATE 200 (same as ATE Gold??) for my mechanic to use when he replaces my brake fluid. I got 1 liter from OG Racing...is that gonna be enough?

Also, I only do street driving...spirited at times, but mostly not. I've not changed the fluid in the 2.5 years I've had the car, and the brakes feel great. Even if the brakes feel great, should I be changing it every year or so anyway...kinda like I do with my oil...every year regardless of miles?

Yes, change & bleed your bf at least every 2 years or so, even if not visiting the track. Brake fluid absorbs H2O via the humidity condensing out of the atmosphere. This occurs inexorably and you do not notice the slow & steady degradation of braking performance in normal street driving. Also, fresh bf minimizes the material wear on seals in the hydraulic master cyl. Regular bleeding & replenishment will extend the total life of the system & its components. All this translates into performance, reliability & safety.
