Years ago ATE had a blue colored DOT4 which made it easy to tell when to stop bleeding brakes. Are there any other brake fluids with coloring in them? Last I heard ATE is "banned" (maybe that is too harsh of a term) from selling the blue fluid.
Only if you don't change it often enough.Pretty easy to tell when the new fluid is coming out when it changes from dark to clear.
Brake fluid must be clear or straw colored (DOT regulations).
Every 2 years is recommended. I've seen it turn light amber in 6 months. After 2 years it shouldn't be too hard to tell. Regardless, if you're using a typical quart bottle of fluid, I've found it takes less than a quarter of the bottle per wheel before the fluid comes out clear. Dole it out accordingly, and you don't have to worry about seeing the color change.Only if you don't change it often enough.
That's not a politically correct term anymore.years ago margarine could not be colored, it was white.

I use it to alternate between clear/amber and dyed when doing my 2 year flush.
You only need a drop to tint a small can.

Using the correct brake fluid (either DOT 5 silicone or non DOT 5 silicone) is such a critically important concern for automobile safety, they regulate it so there can be absolutely no confusion as to what fluid you are using. It is either purple, or not purple. If it isn't purple is can be anywhere from clear to light amber in color, but no matter where it is on that spectrum, it should be extremely obvious it isn't purple.Really? what's the wisdom behind that? I think I have seen it listed on Tire Rack as "amber" in color.
Thanks for the explanation.Using the correct brake fluid (either DOT 5 silicone or non DOT 5 silicone) is such a critically important concern for automobile safety, they regulate it so there can be absolutely no confusion as to what fluid you are using.

Making it blue (ie. pretty close to purple) is incredibly dangerous and would almost surely result in some deaths on the road.
That should be enough, but not everyone has the critical thinking skills you and I may employ.Silly me, I was under the impression that reading the label and knowing what you are buying is the key to avoid using the wrong product.
