Is the brake fluid in the ABS system sealed off from the brake fluid in the rest of the braking system? If not, then after the normal replacement of the brake fluid (not flushing the ABS system), the concentration of moisture and contaminants would be higher in the ABS system than in the rest, causing a chemical gradient. Thus, diffusion would naturally occur to balance out the chemical gradient.

Now, if the two sides were only exposed to each other during ABS system activation, then diffusion stands little chance of happening. The obvious solution is to autocross your car frequently and brake heavy in every corner.

your theory as well your car are your own. Do what you think best.

And NO brake fluid and moisture and other contaminates do not apply to your thoughts. But nice try. You left out a few things in your thoughts but I am not going to now talk chemistry,


AT this point as they say you can lead the proverbial horse to water...but...

and

this, my responses at this point or yet another proverbial phrase of beating a dead horse.


Try this in different ways and area's of samples and come back with better idea's and perhaps knowledge for similar experience references?

Good luck for all members and their brake fluid refreshing exchange.
For me the correct way of flushing brake fluid has Already Been Serviced in most of my cars.

Physics of chemical gradients isn't a theory.

Dude really I am talking about your thoughts/theories on the ABS systems and the brake fluid in that system. WOW!!! Not talking about what many of us learned learned at age 12 from a chemistry set playing with it in the bathroom. (poking fun.. I hope you get the idea?)

I post on threads to help and not have to defend all my responses.


Please... Go re-read EXACTLY what I said and not what you think I said!


When member frick up their ABS system it won't be because on this forum and this thread I did try to set them with information and cautions.

Hint...it is a trick question!

48oz + 0.17 oz = 48.17

0.17/48.17*100=0.353% water

It is far, far easier to do math in the Base12 that standard measurements are based on than the Base10 that metric is based on, and here's how:

What's half of 10? 5.
What's 1/4 of 10? 2.5
What's 1/3 of 10? 3.3333...
What's 1/6th of 10? 1.3333....
What's 3/4 of 10? 0.75

Now,
What's half of 12? 6
What's 1/4 of 12? 3
What's 1/3 of 12? 4
What's 1/6 of 12? 2
What's 3/4 of 12? 9

See the difference?

Now, people claim that metric is easier because changing units just add or subtract 0's. Well guess what? When you start your math in one unit, YOU STAY THERE. Changing units, even in metric, just screws up the overall calculations!

How many picometers in a gigameter? The question is moot: literally nobody cares!

Nice try and a very logical formula but it is the wrong answer. I gave the hint that it is a trick question.
My point was and your response supports that on forum like these many members do not fully read the responses from members and look for what they want and read much more or incorrectly what was written. Nothing personal I appreciate the though you took to answer it. And if I had worded it differently your answer would have been dead on correct!

If you want to PM me for the answer instead of burning out your brain with this feel free.

theblooms,

Ever heard of "three two" beer? This is beer that is only 3.2% alcohol as sold in grocery stores in states like Colorado where real beer (i.e. 5% beer) has to be sold only in bonafide liquor stores.

Except, it isn't "three two" beer. I'm one of the few who checks labels and looks for things like 'alcohol by volume' (ABV) and 'alcohol by weight' (ABW) because I've lived and worked in various foreign countries and want to know how to argue mundane crap like who brews stronger beer.

In the U.S. we used to have ABW on the label and our beer said 4.0%. Then we switched to ABV and our beer said 5.0%. So all of a sudden we got the respect from our German friends (one of the places I worked) because our beer got stronger. Except it didn't. We just labeled it differently.

Ethyl alcohol has a specific gravity of 0.8 that of water, meaning it only weighs 80% of what water weighs. So, if you have a solution of 19 parts water and 1 part alcohol, the alcohol percentage can either be listed as 5% by volume or 4% by weight.

So, for our sneaky beer manufacturers who sell in grocery stores, their ultra-low alcohol beer (gee dad, it's only 3.2%!), it's really 4.0% if you rate it by ABV, alcohol by volume. That would be the fair comparison to our regular beer which is 5.0% ABV. But, to make the state government happy (by effectively fooling stupid people in the government) they took the 4.0 number and multiplied it by 0.8 to get 3.2. Just like our old beer was 4.0. They started dividing that by 0.8 and got 5.0. It all depends on what you want to display.

This kind of stuff really irked me when I worked as an electrochemist. My chemistry colleagues just told me to calculate everything in moles because then you don't have to worry about stupid naming conventions by weight or volume or whatever. Moles is moles in the chemisty world and normalizes everything.

Those that tend to have higher IQ's seldom get the correct answer....(I didn't and did what a couple of you are doing now, over thinking the simple solution ) as I said people read things others post for what they want to read and not what is written..
Point you cant have it your way when it comes to the mechanic's of how vehicle parts work. There is a correct way to do things as things were engineered.

The answer to the problem!, (I believe) is 0%, as the water and the fluid are still separate.
