There is a few guides, I did one also. You need to be a member though. Dot 4 is fine even on track. You get what you pay foe obviously

We do our cars with CL Brakes Dot 4. Copes with my late braking technique anyway and for the price you can't get much better. The Dot rating is a minimum standard and most top of the range fluids will far exceed this.

blimey thats great value!!!!!
I'd have said ATE super blue (it will stain your lines though which is a mild ballache) as its a great fluid for minmal cash.
Although recently I've been using just pikey 5.1 fluid from the local motorfactors Think its about £3/litre and not had a single boiling moment etc with it and given its soooooo cheap, bleeding on a regular basis if it were to boil makes no odds imho

not at all actually! have you ever used them? and they sell pretty much everything anyway so the law of averages would say that they would reccomend something they sell
I think having to replace it isn't really the reason why people dontwant their brake fluid to boil....
note, I've not managed to kill my pikey £3/litre 5.1 stuff and I thrape the life out of my brakes...Managed to boil some normal dot 4 when bedding in some PFB 97's ffs, didnt get a hint of that with the 5.1
Not a huge fan of the OO lot, their 'advice', but thats my humble opinion and you all can have yours too

brake fluid is not particularly rock science.
Minimum specifications for DOT 4
Dry Boiling point 230 °C (446 °F) , Wet Boiling point 155 °C (311 °F)
DOT 5.1
Dry Boiling Point 270 °C (518 °F), Wet boiling point 190 °C (374 °F)
Dry boiling point is as it comes out the tin, wet is once its absorbed 3.7% water.
I'll use CL Brakes as an example as I have it to hand
Its a DOT 4
Dry boiling point 325 Deg. C (617 Deg. F.), Wet boiling point 195 Deg. C. (383 Deg. F.)
so as you can see it exceeds the minimum specs for 5.1
Off the top of my head Castrol SRF is THE best performance brake fluid for wet boiling point on the market, but CL brakes is better dry.
All the specs are easy to find on the web and theres little advice that can be given. Buy the best you can afford and personally I would be changing it on a yearly service minimum.

Interesting kev. Dot4 super castrol works very well, even when not bled prior/after track days. Lol
