Hey all,

I noticed the other day that my clutch resevoir was empty... i tracked it down to the little spigot which is in the top of the master cylinder for the hose to push on to. I am hoping to just replace the spigot as there is nothing wrong with the master cylinder otherwise.

I checked on realoem and the part is there - but no part number is listed and i cant seem to find anything through google. Anyone know how/where I can get hold of one of these fittings?

As long as the fluid didn't get too low as to affect the clutch operation, it should still be OK, but if air was drawn in, and the clutch pedal went to the floor with no resistance, the piston seal in the cylinder will have been pushed into the 30 years worth of gunge and debris at the end of the cylinder, which is likely to damage it. The dislodged debris can also find its way down into the slave cylinder, finishing that off as well.

Thanks Briann

The pedal never went to the floor i just noticed the resovoir was empty before it got to that point. I have the master cylinder out of the car now so will be careful not to push the plunger in.

What's the part number for #21 by the way? It's always greyed out on the diagrams I find on RealOEM.
