Pagid DOT4 is good with a dry boiling point of 280c if I remember correctly or the stuff Brummie on here sells is meant to be as good as it gets for a road/track mix, boiling point of 320C I think or you could go and get the race type fluids but they need changing rather frequently for my liking.

Thanks

Yeah not keen on dumping the fluid to often for track days sure but not for light road use so racing stuff is a no go. A good road/track product would be fine.

Oh and how much does the whole system hold as well?

I have used Halfrauds Racing Fluid for the last three years, brilliant, no problems and off the shelf.

I know nothing but someone wrote that DOT 4 is good for clutches and 5.1 for brakes.

My own opinion is that if you don't need to change the brake fluid after a Track Day then you're not trying hard enough.
(This coming from a man who never got his discs above 375 Deg C. until he started measuring ;o) )

ignore dot and look at temp rating

Ta !

Do I remember you distributing some special pads that, at the time, were only avaiable for the front ? Is there a pad available for the rear, too, now ?

Ta again !

I have just started using ATE Super Blue (DOT 4).

It has a dry boiling point of 536F, and a wet boiling point of 396F, sits 20°C over the DOT 5.1 standard and surpasses this standard in nearly all the other areas.

Finally Super Blue makes your fluid changes really easy as you are left in no doubt the system is fully purged when only 100% new blue fluid is coming out of each corner.

They also do a yellow colour with the exact same spec, so you can alternate between blue & yellow every 2 years when you change your fluid.

Quote part number 130339010 at any Euro Car Parts and hand over £14.52 for a litre which was ample for a full fluid change on my Chimaera.

Out of interest, boiling point is 308 degrees and it's a Dot 4.

Thanks all, Lots of food for thought. This is way down on the jobs list for winter so lots of time to think it over and get round to it.
