Brake Fluid
For those of you who have changed pads, rotors, brake lines and/or replaced brake fluid or other brake related components, what brake fluid did you guys use to replace the factory fluid for your specific application? Did you guys just use the factory Honda Brake Fluid or another type or brand?
My setup will soon be Powerslot Rotors all the way around, Hawk HPS Pads all the way around, Goodridge G-Stop Brake Line Kit (from TireRack)
With this setup, I don't know what kind of brake fluid I should use.
I will be going to my first track event on September 23, but other than that one track day, I will rarely be going to the track or autocross.
What are your guys' thoughts and/or suggestions?

No idea but I'm sure someone at Honda-tech will answer your question. Or you can go to a Honda dealership and look on the label at the back of the brake fluid bottle.
P.S I have a few bottles in my garage, I'll check tomorrow morning

Valvoline Syntech DOT4 - cheap, easy to find, and good.

Thanks anyway JeffTSX

My brake bleeding preference is the "vacuum" type unit to draw fluid out rather than using pressure to force it out.

I use ATE Super Blue or Gold depending on the flush. Honda System Safe in the last 2 Type-Rs (2000 and 1998) and the previous Integra. Great Boiling point and 1 Liter can be had for $10-$12 and will flush the car at least once.
I use the pressure method for bleeding but I prefer to use a soft silicon hose on the bleeder screw submerged in a small bottle. It allow you to release the pedal without closing the screw since it pulls fluid back instead of air. I can elaborate if those without a vacuum system are interested

As for specs, I now have the spec sheet in front of me...
Wet Boiling Points: JTso's link already provides the same as I have.
Viscosity (measured at 212 F):
DOT 5.1 - 2.1 mm2/s
DOT 4 - 1.5 mm2/s
DOT 3 - 2.1 mm2/s
So viscosity is the same for DOT 3 and DOT 5.1 at 212. It is slightly lower for DOT 4.

I've been using Motul RBF600 brake fluid in my Prelude since I changed the brake lines in 1999. I haven't had a problem with it. I remember that there were couple of years where I didn't even change the fluid and it was still fine.

My long-term independent testing of my Integra shows that Valvoline isn't a problem and my MC is still good and the car still stops from triple digits. Unless they made the system seals out of some super-duper material that lesser Acuras don't get, then I'd say it isn't an issue.

There are a ton of variables that are different, not to mention VSA. I'm not saying you should stick to OEM, just saying that I haven't seen a reason to say switching is better.

The fact that my front calipers don't have much left in the way of rubber dustboots tells me that OEM fluid would get mighty hot.

I looked at the cap on the brake fluid reservoir today and it said to use DOT 3 or DOT 4.
But in the manual it says to only use Honda DOT 3. But in case of an emergency, DOT 4 can be used but has to be replaced with Honda DOT 3 brake fluid as soon as possible.

Well, if you are doing modifications to your car and replacing certain non-stock items, you are already not following what the manual says anymore. Make sense?
Just try one type of fluid and see how it works for your particular kind of driving. Then make the appropriate changes accordingly. The fun part of modifying is you get to play with many different components and learn something in the process.

good thread for me... I am changing my brake fluid tomorrow and was looking into getting that Valvoline SynPro that TSX3pedal linked.
Still undecided if I'll go to that or stick OEM fluid....

I highly recommend changing per the spec. time and/or mileage.

I am at 51K miles and a month shy of 2 years.
Tomorrow my friend is going to do the following on my car for me: (I really need to learn this myself)
* replacing the rear pads with Hawk Ceramics (already had the front pads AND rotors replaced about 20k miles ago
* Drain & Fill Tranny Fluid
* Drail & Fill Radiator Fluid
* Bleed brakes, flush/clean and fill
* Oil Change
* Cabin/pollen/HEPA filter change
* Cleaning K&N Filter for the CAI
busy busy
based on reading this thread, I really think I will go with the Valv SynPro.. since some of you who have changed your brake fluid already are finding it baked and crappy. I do a lot of city driving and sometimes brake hard ... we'll see how things go
p.s.- my front pads did not need to be replaced- had about 90% of pad... I just wanted to put on the HAWKS and my rotors were so warped at 30k miles I had to replace them...
