Not convinced about my brakes?

The 5.1 is just a semi synthetic version of Dot4 and can be mixed...Im sure Tony will correct me if im wrong!....  If you are boiling your brakes, then this can be because

the brake fluid you are using might as well be made from Tea
you are getting air in the sytem which leads to
you are getting water into the system.

Why compromise on the simplest of items?  yes its another £20 but how much to replace a wing if you dont manage to stop?

Go for the AP600 it has a very good boiling point....and it will make you car go :Thumbsup!

If you really want to go the whole hog then get some Castrol SRF

As you can see, not cheap at all! But it\'s a seriously good fluid, I think it\'d be nigh on impossible to boil that when it\'s fresh! And will mix with Dot4 and Dot5.1...

Ive always been perfectly happy with carstrol super dot 4 (SRF i think)...used it ony car at the nurburgrng and didnt get any fluid boiling...also used it at croft and snetterton with no issues....i was gonna use moutl rbf600 (i think thats what its called) but the castrol was readily available and not that dear either

5.1 is Dot5......It is so hydroscopic that you run the risk of boiling your brakes, especially in a road car with the continual starting and stopping (yes I know thats what they are used for ) as that is when the moisture gets in.  A quality Dot4 is far better....I dont even run it on my car  I dont believe that the necessary frequency of changing the fluid out-ways that of the implied benefits.

Maybe the stuff in mine isn\'t 5.1 then - checking the label it\'s R600, not sure what the spec of that is!

Here you go Iain,

We have used this for the last few years and it exceeds all the above on this thread and is compatible with normal fluids.
