The forgotten fluid, what is it, Brake Fluid, one of my pet peeves!!!!
Take the time to look through this easy to read & understand mini tutorial, on brake fluid & scroll down to "find out where you likely are on the boiling point curve"!!!!
The info could save our necks, if we drive fast, on in the mountains, or with heavy loads, or have never changed our brake fluid & have to make a panic stop, only to feel that pedal get soft, or go to the floor, because absorbed water in the brake fluid lowered it's boiling point!!!!
Keeping the fluid changed on a regular basis will also cut down on internal system corrosion, as absorbed moisture will be drained out with the old fluid & thus won't remain to cause serious problems.
Lots of good info about brake fluid there, like why silicone brake fluid shouldn't be used for street vehicles, why DOT-4 fluid can quickly loose half of it's wet boiling point with only 3% water absorbtion, why all DOT-3 fluids aren't the same, ect
I know where I am on the curve, as I flushed both of my rides with Motorcraft PM-1 DOT-3 fluid last summer. I do them every 3 years.
Enjoy the read, I sure did.
