Dot 5.1 has the added benefit of being adaptable to a variety of rubber compositions.

Dot 4 oder dot 5.1. I know not to use dot 5 but what has been the improvement with dot 5.1? Wat are the benifits of changing from dot 4 to dot 5.1 : I made myself a container to catch a leak from the master cylinders.

I use dot 5.1 because it is clear, this is another (some kind of better) dot 4. I run ap600 in my track car which is a dot 4 with a high dry boiling temp (over 300c). The brakes on my bike are crap house.

Dot 4 brake fluid is preferred by many people because it can resist more heat in comparison to the weaker dot 3 brake fluid. Die dot 4 oder 5.1 ist ja scharf auf wasser zieht es an und einverleibt sich die gerne. Dot 5 ist nicht mit den oben genannten dots mischbar, da es auf einer silikonmischung basiert!

It is, therefore, easy to make an upgrade from the other dot 3 and dot 4. It is used exclusively by the us military for this reason. It's far superior to 5.1.

Dot 5.1 and 4 are interchangeable, but it's good practice to flush all the old stuff out anyway. It's also difficult to find this braking fluid in some auto parts shops. Dot 4 is the successor of dot 3.

The label claims to be compatible with dot 4 and dot 5.1 systems without mentioning anything about dot 4+. There is no reason to get older version, except for price, but it's only a couple of $ difference. The brake fluid bottle i have readily available is dot 4;
