Master cylinder pushrods.
sdh2903 - 30/12/15 at 05:13 PM

I'm looking at various tandem master cylinder options for my build. The fiat 124 or later uno ones seem popular and look an ideal bore size at 19mm. However none seem to come with the pushrods. My question is does antone know if they are all a standard size? 5/16 seems to be popular but m8 are available too. The cylinder I'm looking at is the one below

+1 for pushrods for these same cylinders

if its not a threaded rod then 5/16th (7.9375mm) is equivalent to 8mm
in the same way as the nominally 19mm cylinder you linked to, is actually 19.05 ie exactly 3/4 inch.

The thread only has to match the clevis thread where it connects to your pedal. At the cylinder end it's just rounded to fit into a cup/hollow in the piston.
8mm and 5/16" are similar and both diameters will fit the cylinder, just choose one to match your clevis.

Thanks, I've ordered both the cylinder and rod now. Hopefully they'll slot together nicely
