Yes, I searched, and most information was about replacing fluid after a hard day on the track. I did that the one day I did 4 hard 20 minute sessions, but since then the car has only been on a road course for about 30 minutes.

My question is, if you are not tracking and only putting 3-5K on your car every year, how often should you replace brake fluid?

I take that just sitting around in a humid climate like Houston will eventually result in water in the fluid, yes?

Is once every 2 years under such conditions OK, or should I replace more often? It has been 9 months.

 

Sean.... I mean come on.. Who actually uses their brakes?!

Actually I'm kind of interested to know also. I've had my car almost 2 years and I've never replaced the fluid, but I NEVER road race.

 

I have herd that if under normal driving, every 50,000 miles or 4 years.

 

Look at the color, is it dark? You can probably go on the track one more time.

 

In the manual , they say every 2 years .

OK...if I am replacing fluid and not tracking, what should I use? What is the best STREET brake fluid?

 

You can use Motul, it's not expensive and very good.

 

When I track my car for two days, I bleed the brakes after those events.
I flush the brakes and slave cylinder once or twice a year when it is tracked. My concern is moisture in the fluid, not the color. In your case with only one day on track and it was flushed 9 months ago. I would leave it alone, but if tracking again would flush the brake cylinders.

If car is just used for street driving, flush, brakes and slave cylinder every two years. I use ATE DOT 4 fluid for both track and street.

 

If cost is not an issue CASTROL SRF

 

Motul RBF600, used it for few years now, some serious sessions, no issues!

Need to find that pic someone got of me at track with rotors glowing, awesome shot!

 

Correct. Every 2 years.

 

No MORE than every two years, less if you are tracking and put the fluid under heat stress.

It is not so much that the heat will degrade the fluid, but older fluid that absorbs water will boil faster when you hit the track. So new fluid PRIOR to the track.

PS Water absorbed into the fluid can also accelerate breakdown of components in the brake system- so a flush isn't just for performance, but to maintain system life.

 

But isn't the Motul primarily for tracking? Better under extreme conditions but will not last nearly as long under ordinary street conditions.

 

If you want cheap street fluids, ATE Superblue or Type200.
Change once a year.

 

Talked to Rob K about this. Based on his recomendations I am going to change mine today with ATE Super Blue, that way I know my system is completely flushed and next year I will do it with Motul RBF600 which is a gold colour, each time you will know the fluid has been completely flushed cos of the colour change...anyway that is what I am doing and I don't track my car.
