Took my car for a bashing the other day, after 5 mins i was experiancing brake fade and thought wtf?!? Couldnt be the brakes, tested my fluid and was showing a 4% +  moisture content,Obviously i boiled the water. Changed fluid , putting DOT 4 in and went a some country lane thrashing for the night, was fine. I mean i cant see you having problems with DOT 4 unless you do track days maybe? I still think it will withstand that.

You are joking arent you.... I boiled good quality dot 4 fluid the same day I changed it with 6 ... yep six high speed stops.

All the 4motion (1400KGS ) is 5 or six stops from 120-130 + and the
pedal willl hit the floor.... the brakes are grossly inadequate for any
serious driving...

From what I have investigated, your only option will be to user DOT 5.1 fluid which will increase your boiling point by 10 degress depending on the brand of fluid that your go for.

http://www.h-e-l.co.uk/HEL_Performance_Motorcycle_Brake_Lines_Brake_Doctor_FAQ.htm

I have also read that just having fresh DOT 4 in your pipes, will be just as good a DOT 5.1 so I don't know if it would make any difference in your circumstances.

Also, not sure if it will help with the boiling, but have you though of trying braided hoses ?

For fluids, this is what google throws up

I run a dot 5.1 fluid on my race bike and never had any problems with the fluid boiling / brake fade and thats with 40 minute stints on the track at race speeds with mega hard braking. Brakes even get hot enough to melt the copper grease on the back of the pads!

Highly recommended but has a downside that it needs changing once a year.

Used to get bad fade on my old Calibra, new dot 4 fluid cured that. As far as I know dot 5.1 is a bit ott for the road but may be what you need.

Mad! If you can boil dot 4 in a golf that easy i wonder why they put it in say super saloons, M3 , M5 etc. Bit of a hazard if you ask me.

Just about to use Motul RBF600 dot 4 my self in the R32, did a bit of reading up on the net and there seem to be 2 choices, the Motul 600 and Castrol SRF.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" /><o:p></o:p>

<o:p> </o:p>

The Castrol is ment to be the best but at ?40 a tin its way too expensive and your going to need 2 tins, the Motul is ?6.99 for 500ml and you need 3 bottles. The Motul seems to go down well with the Scooby and Lancer boys so im going to give it a try, im also having some braded lines made up to try improve feel a little more also.

cheers

I'm doing a trackday at Oulton Park, hence why I want to get my brakes sort.

I have also emailed Opie Oils, to see if they might be able to do a discounted price, to which they have replied they should be able to do 10% if we can generate 4 orders i.e. 12 bottles.
