Brake Fluid: DOT 5 and DOT 5.1 actually different?

[Rineheitzgabot]

Are these two ratings different or the same?

Use Dot 5 only in your bike....5.1 is different

Dot 5.1 is for the Dot 3 and Dot 4 application...its not meant for mineral or silicon type systems

What Knothead said. I made that mistake once cause there was a $8 difference!
