Clutch slave cyl

[HondaRed66]

At the connection point of hose to slave cyl
I have a fluid leak. Now I installed a copper washer/gasket but it still leaks. Is there a different washer/gasket material that I don’t know about?

Welcome to the best web resource for the Fairlady Roadster
Either a copper or aluminium washer should work as a crush washer.
Is the leak from the connection or further back on the flexible hose crimp?
You may need a replacement flex hose.

If you are certain of the leak point at the crush washer, you can try loosening and tightening it again.

You shouldn’t need it, but if nothing else works and it’s not the hose itself then you could try some Teflon tape on the threads.

Leak is definitely at the crush washer.
I’ll give that a try!

I was kinda thinking the same thing.
Never had to do that before but it’s worth a shot!

So i tightened, loosened , tightened and no more leak!
Thanks all

The topic of the copper crush washer has been discussed before, but EVERY time you use one, whether new or used, you should temper it to restore its malleability. All you have to do is heat it to red hot (it takes about 10 seconds with a micro torch) and then dunk it in water. Doing this to steel makes it hard and more brittle. Doing it to copper has the opposite effect.
