OK what is the best brake fluid for normal running about, not track work or racing around of any kind(thats cus I'm an old fart)
if I upgrade do I need to do a double flush, meaning flush with the new fluid then flush again
just to make sure that all the old fluid is replaced.

It doesn't really matter what type you use.
Defently use DOT4, DOT5 I find doesn't last as long.
Around the city you will not notice the diffrence!
But if you want a good one is made by Motul, can't remember the specific name, it's for racing use, but it is really good and is a DOT4.
You shouldn't have to do a double flush, i think 1 bottle of brake fluid should be fine to do a system flush. You can do a double one, but it is not really neccessary.

Brake fluid is Hydroscopic - meaning it absorbs water. Over time if it absorbs to much water, you get a squishy pedal as water is compressible as opposed to brake fluid. I did a how to on flushing it a while ago, you'd have to search for it. There is a certain technique to it.

Although you wount see the water, there will be small water particles in the fluid. Over time the chemical make up of the fluid will also degrade reducing the boiling point of the brake fluid.
Thats how i understand it anyway.

Unless you use something synthetic like Castrol SRF.............
An expensive option but I have never had any problems in any of my cars.
