How frequently should racing brake fluid be changed?

[MarkCup]

I've got some Motul RBF600 I'm going to change to before Oulton.

Is there any reason why I shouldn't use it in my Cup?

I know it's hydroscopic (sp?)...how long will it last before it needs a change?

Its DOT 4 by the look of it so pretty much standard fluid so no reason why not. When its in the brake system it shouldnt take on a huge amount of moisture you just have to make sure it's kept in a sealed container before use. DOT 5 silicone fluid is the stuff some people arent so keen on.

Just ask me to test the boiling point with my brake fluid tester.

Bump...

Anyone know how long in normal daily use + 1 trackday per month racing brake fluid can be expected to last before needing a change?

Am I looking at just a few weeks to be on the safe side...or is it good for longer?

Ages, just give them a bleed now & again

If your tracking it hard, I would change the fluid every other session.

how do u bleed?

if you are using the car daily and tracking the car then I'd recommend bleeding/changing fluid every 18 months. once you've got the knack, it's a simple job. Reason - because brake fade kills!
