I just figure it'd be easier to run the same fluid in both if I can.

I run ATE in my brakes and works awesome. I tried it in my master and within 4 months, the rubber seals inside were mush. Mcleod then told me not to use it as it would eat up the rubber in their adjustable masters.

Hrmm I just flushed my system this weekend, the master side down to the quick disconnect was black, but when I reconnected after a bench bleed(on the top half), the fluid that came out the slave was yellow.... Wonder why? Still having the people stuck to the floor on high rpm shifts though...

I have always heard it was a combination of the properties of the fluid... and on the F-bodys the clutch line goes right by headers in most cases. that extreme heat aids in the breakdown of clutch fluid.

I'm gonna have to try somethin different, I believe they changed the slave when the did the clutch on this thing(right before I purchased the car), The steel braided line has a rubber hose around it and runs under the heat sheilding. So I'm stumped, Pretty sure the fluid in the slave itself was clean though, the mast up was black as day... Err Night.

Hey guys I have a question, and its actually not pertaining to an F-body. I would like a Mustang guy GT/Mach1/Cobra to chime in... are you guys having these kinds of problems with your clutch hydraulics? I have not personally been on any Mustang forums but I am very interested to hear. If not... what is the problem with our cars then having these issues?

Oh really? I've driven a Cobra, several GT's and Mach1's and they don't seem to have a stiff clutch? I would think without hydraulics they'd be pretty stiff. Do they have some kind of pulley system on the cable?

Hmmm... well I've got a Spec 3 in my car and the Cobra/Mach1's weren't as stiff as this... but i don't consider it stiff anyways (i've got big legs lol). Only gets to be a pain when sitting in traffic for 45 minutes lol. Well that explains it, learn something new everyday. I wonder if we could adapt that to our cars? Because I wouldn't mind getting rid of the hydraulics all together.

I've seen many mustangs have issues with their clutch cables too...heat is a big enemy there...once the cable gets too hot they're screwed. the linkage they use is called a quadrant...they make different ones for different levels of mechanical advantage to the pedal...including progressive ones...I've never felt one that I liked though.

Are we sure that the T56 equipped Stangs ('03-'04 Cobras/GT500s) are still using the cable quadrant system?? I thought only these were hydraulic, like ours?

I'm pretty sure the Spec stage 3 uses a stock pressure plate ( My old one did ) They just ground off where it said LUK and put a sticker that said spec. Other than that they were the same so it wouldn't change the pedal pressure.

Ahhh ok well I didn't put it in the car previous owner did so I wouldn't know. I'm just very curious if the Cobra's have a hydraulic clutch... and if they do if they experience the same issues we have?
