Now that makes more sense to me...I haven't had the flecks either, but will look for it and also check temps. Thanks for the info.It's all about protecting the brakes from the clutch, not the other way around. First, S197's have a history of cooking the clutch fluid because the OEM fluid line is too close to the exhaust. Second, if you've ever seen little black specks in your brake reservoir, they're from the clutch lining. Particles of clutch lining stick to the extended slave cylinder and get pulled past the seal into the cylinder. There's enough clutch fluid flow up and down for them to migrate up to the reservoir. So, a separate reservoir keeps cooked fluid and bits of clutch lining out of the brake circuit.
My GT500 never had a problem with cooked fluid, but I did have black specs floating in the brake reservoir. I sucked them out with a hand held pump and replaced the fluid, but I never got around to splitting the circuits with a separate reservoir.
