Question Brake fluid

Thanks in advance.
I have read some of threads on the brake bleeding process.
Wayne's book and the Tech article suggest bleeding each caliper more than once.

Our host offers the Ate brand in a SL Dot 4 and the Super Gold Type 200 Dot 4
There is information on the Super Gold referencing boiling point numbers etc.
And a $1.23 difference in price.

Is the Super Gold strictly for racing and not to be used in a street car?
Or a better option?
And how many liters to completely flush the system?
Thanks again.

I have used Ate 200 for street use for years. Great product. I flush the system including clutch line yearly. A can and a half, maybe 2?

I use ATE 200 and do the same thing.

The SL grade is for use with ABS Systems and has a different viscosity profile.

FWIW, I flush my brake fluid annually. This week I decided to replace my brake hoses (they flowed fine a few months ago when I did my annual flush). I cut them open and this is what I found:

The two ones on top are from 1991. I do not know the date codes for the other two. They looked pretty good.

+3 for ATE Super Gold 200. Street use only for me these days; love the stuff! I Bleed the brake system every two years using the Motive Pressure Bleeder. Makes it a simple process for one person.

I usually only have to bleed each caliper once, occasionally I will have to do them twice. I also tap the caliper with a hard plastic headed mallet as I bleed; seems help but who knows.

Just stay away from the DOT 5 silicone stuff. Gives a soft pedal and you will have great difficulty flushing it out of your brake system.

200 is original fill on most German cars, it has a higher wet and dry boiling point than the SL

The low viscosity fluid is SL.6

To further confuse the issue there is also an ATE DoT 5.1

ATE 200 is the best street fluid,

Castrol SRF the best track fluid but also provides the longest useful life expectancy in street use

both are DoT 4

Thanks Bill. When I was doing track events I did use Castrol SRF in my 911...very good stuff!

When's the last time you changed brake fluid? ATE Blue hasn't been available in the US
for several years. DOT rule.

For just your brakes, 1 liter should be adequate.

Back in the gold to blue back to gold days, I found that less than 200 ml from each caliper was all that was needed for a complete color change. That is 800 ml or 0.8 liters.

Ah, the good old “ blue & gold days”. Gone, but not forgotten. 😥

If using a pressurized bleeding system, plan on sourcing more than the single liter needed to refill the system.

The Motive is a fine way to do, but do yourself a favor and do it dry, in other words don't introduce fluid into the Motive, just use it for pressure

Really? I find a liter more than enough. I fill the reservoir, plug the overflow and use the Motive to pressurize the system and top up the reservoir after each caliper.

if you belong to one (or more) of the 3-4 ethnic groups noted for cheapness, you can make your own system from a $10 garden sprayer, tubing, and an old m/c cap - no need for the Motive
