Brake pipes for locost/sierra... (size)

[cps13]

Hi,

I am looking into building a locost style car. I have had a look a brake servos/cyclinders etc for sierras.

Does anybody know what size brake pipe would be needed?

Thanks!

Brake pipe is not the issue as there is only the one size.
What you must find out is the thread size and type for all the bits you will use as you may come across a mix of metric and imperial fittings dependant on the age of the donor parts you will use.

3/16" OD Kunifer brake pipe will be the norm.
