i'm running greenstuff and brembo discs and had no problems on track or clear back roads over pennines (a686) so probably is fluid
Sorry to gatecrash our post mate and if this sounds silly.
But if his pads have fried themselvess, why would it come down to the brake fluid ?
Fair enough if you use your brakes enough you can boil it, but the fluid wouldn't cause smoke :S thats the pads not coping with the heat.
I guess Red Stuffs may be better for a track day, as i think they need a fair bit of heat in them to work properly don't they ?
And can withstand higher temperatures.
But say you used Red Stuff pads wit Brembo Max Discs, would you warp the discs with the heat involved in braking ? :S
