Cross Reference for Clutch Master and Slave

[Steve Meltzer]

The slave cylinder on my GTC is leaking and needs to be rebuilt, or replaced. Is there a cross reference to say, Alfa or Fiat for this?
The master cylinder seems OK, but should I rebuild it at this time, or not? Cross reference for that? thanx steve

If this is what you mean Steve give me a PM
can be bought at every good supplier new.

Hi Cornelis,

Isn't that the clutch master? Steve's slave cylinder is leaking.

Steve, Why not just buy the correct Ferrari part? Push rod lengths and spring attachments might be different and you won't know until you install it, but do you want to do things the hard way?

The one piece that is often not replaced is the flex hose, which is a pain in the butt to change. Now is a good time to replace it.

Tom. I'm with you and let me carry that one farther. Any time any of my customers need hydraulics replaced I replace the master, slave and hose or hoses. Sure as hell as soon as you replace one component the other one is sure to fail.

Well Tom and 8339 the question was concerning CLUTCHMASTERr and SLAVE.
Both parts can be bought at Fiat 2300.
But are not cheaper there.

My attitude :I always prefer to bay new as long its available, and overhaul the org. one in winter as spare .

When you invest around 220 euros you have BOTH all new.
and can drive one week later again.
and that counts I think.

Steve next time pic of manual please for better understanding for foreigner( me)

Sounds like a new master and slave are readily available and might be the best way to go. Is that right? Tom, the hose you're advising me to replace is from the reservoir to the master, right? It is my slave that's leaking, tho' the master (which Cornellis featured) does have this weird corrosion/crud on it's outer, visible surface, but isn't leaking. thanx. s

Steve: The hose they are telling you to replace is the high pressure flex hose that goes from the hard line under the car to the slave. When you are ready to bleed the system, let me know as there are tricks to bleeding it out. You might want to think about converting to silicone fluid at this time also.

[Steve Meltzer]

Thanx Dyke, I bought a new slave cylinder, but, for the moment decided to leave the MC alone. A new one is $250+, and since mine is working fine and it will no easier nor harder to do that later, I decided to wait. I'll change that hi pressure hose as well. thanx. steve

OK, thanx, Cornellis. At least I didn't get ripped off. Paid $75 for the new slave from T. Rutand's. Well, there's an anomaly: for once a Ferrari part was less than a Fiat. Whata deal, maybe I'll be two. s

No silicone fluid. Castrol DOT 4 is the way to go.

Gentlemen,

why not using silicone brake fluid for clutch operation, any problems?

[DWR46]

I have used silicone fluid in all my personal street Ferraris for both brakes and clutch since 1977. Absolutely no problems. I change it every 10 years out of guilt, but have never seen a real need to change it. I also do NOT flush or dismantle the systems before installing the fluid, just drain out the old and put in the silicone. Silicone will not work with ABS systems, so do not use it in cars having ABS brakes. We do not use it in our race cars, due to its having a temperature "window of compressability". If you want to read a well researched and objective article on silicone fluid, look at http://www.buckeyetriumphs.org/technica ... /Fluid.htm

With all this said, I am going to set back and watch all the screaming and yelling.

[Steve Meltzer]

Really, there should be no problems using it and it has distinct advantages over DOT 4 stuff: won't corrode paint should you spill it, never have to change it again and very high boiling point (more applicable to brake use, than clutch, of course). However, and there's always a "but", it's pretty expensive, compared to DOT 4. Most importantly however, it's tough to bleed. As I understand it, and all you chemists and CEs, don't hesitate to chime in, it entraps air bubbles; that was my experience the one time I tried to use it in an old 'Vette. I think you have to pump the pedal painfully slowly to keep from getting this entrapment effect. s
