use dot 5 fluid as it has the highest boiling point and better water resistance than the lower number dot fluids, and will not cause any harm

In one day I changed to dot 5, grooved discs and budget Apec pads. Initially I thought the brakes were worse. But get them warm and they were really good.
Put them on the red car but never changed the fluid. I never really ran much power on that car for about a year so never excercised the brakes. Dropped the engine in and then realised they were pretty shite but the discs were worn down and the grooves had nearly disappeared. Fitted black diamond discs and standard Nissan pads and the brakes are shite. Haven't been arsed to change the pads for the pikey ones I used to use. But the pikey pads are twice as good as the Nissan ones. Might be the fluid but I can't imagine that causing a problem for normal day to day braking, that would only show up as a problem after a fair amount of abuse.

i would use dot5 aswell , i used it in my pulsar and was better than the dot 4 that came out, but i wanted a bit more bite (as pulsars are known to have really , really sh*te brakes) so i put in a set of black diamond predator pads , not great when they're cold , but once warmed up, peel your eyes off the windscreen, but what i was going to say was that all brake fluids up to dot4 are mineral based , have alot lower boiling tempreture , when it does boil not only is it inducing air into your braking system but moisture aswell , corroding your brake pipes from the inside out NOT GOOD , dot 5 however is synthetic based , it boils at a lot higher tempreture , i can't for the life of me remeber what it boils at though , i've got it on paper somewhere, but even a hard track day would struggle to make it boil, it's also down to brake set up too, ie the bigger the better , more energy scrubbed off quicker and better heat dissapation through larger disc's

http://www.ebcbrakes.com/Assets/2005ebcintcat.pdf they list the silvia 1.8 zx there quite goot, my brother has them on his vr6, hes got no complaints. i think green stuff are more disc friendly, the red will wear i would think, but i dunno, just a guess
