thanks Eric. That's interesting and confusing with all the numbers. Even though the brakes are working...I think I'll be dismantling them, checking and probably refreshing all the seals and then replenishing with DOT-3 or probably DOT-4 will be fine as I don't think I'l ever be going mental on it.

Funny how if you give it some time before you go back to it, it doesn't seem such a chore.
