Hi Timusin try using MOTUL 5.1. Its the best. IF you can't find motul make sure you use dot 5.1 which is much better than any dtb 4 brake fluid. 5.1 means it can withstand far more higher temps than dot 4 scale fluid. I had serious problems with my motorbike too ( a BMW 1150 GS) due to brake fluoid overheaat and dot 5.1 saved he problem.

Was DOT 4.0 the best available when the RS2 was first produced? The brake fluid container on mine has "Only Use DOT 4.0" written on it.

DOT 5.1 BRAKE FLUID
Non-silicone based, long life and 100% synthetic, DOT 5.1 BRAKE FLUID conforms to the highest standards in brake fluid performance.
DOT 5.1 is specially designed for Anti-Locking Brake Systems (ABS). With a high dry boiling point of 270°C and a high wet boiling point of 185°C,
DOT 5.1 delivers the best brake performance.
Whereas DOT 4 :Glycol-based and 100% synthetic, DOT 4 BRAKE FLUID enables an effective brake even under extreme conditions. The high dry boiling point is
245°C and the high wet boiling point is 158°C. Suitable for all types of hydraulic actuated-brake and clutch systems.

DOT 5.1 certainly gives better performance. I have used ATE Super Blue Racing brake fluid for the past 5 years of so in my Corrado. You certainly notice that the brake pedal remains firmer & there is less fade on repeated hard use. Essential for track days etc. The blue brake fluid also looks good in the resevoir, a good match for the coolant resevoir.
So the one I use is blue and makes it firmer & last longer [img]images/graemlins/wink.gif[/img]

Castrol SRF is a DOT4 fluid, but look at the numbers:
Dry BP = 310 degrees [img]images/graemlins/smile.gif[/img]
Wet BP = 270 degrees [img]images/graemlins/laugh.gif[/img]
Name a DOT5.1 fluid that will keep up with that?

I have just checked on the tin and ATE Super Blue Racing is actually a DOT 4 brake fluid, but still not your normal brake fluid. See link below:
