Seperate clutch fluid reservoir

[Fabman]

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.

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.

With separate reserviors the srf brake fluid would last for years! But I have boiled my brakes numerous times so I am a little sensative. I think the zl1's have a brake fluid cooler. Will IR the fluid next track day

I've had my share of brake woes as well...hard to trust after that.
The fluid boils in the calipers though, not in the master.

It gets pretty hot in the reservoir, I have seen 245 degrees with IR thermometer. There is a lot of radiant heat along with transfer within the brake system.

Thats what I was hoping to improve a bit. Still with my 14" brembos and they really do get some heat into them as they get overworked.

I can 2nd the black specks as well. Since I change to a duel set up , no more black specks.

I have the same one,but never got around to installing. What did you use to cap the stock reservoir nipple , and did the stock hose plug right into this one ?

Used a rubber stopper plug, black vinyl cap and a black heat resistant cable tie. it ain't coming off

Guess who's got the black specks...?

I am sure we could find someone who can build you a second reservoir. Fairly cheap

Are you tying to make me build more parts....?

You probably had them the whole time...

You're probably right, I never noticed them, but then, this car was always an automatic.

Wonder why this is only listed as 2010 and up?

I wonder what would happen if the floaties were left in the master...any ideas?

It really don't need much.

Is the fitting the right size?

 

[Tri-bar]
