P15 brake master cylinder washer

[56Alan]

I have a rebuild kit for my master cylinder which contains a large rubber washer of which I am not sure where to fit. The manual diagram is unclear as to it's location, so I am guessing it goes between the large nut and the spring, can anyone shed some light as to where it should go please?

This might or might not help.

The rubber washer is the first item into the hole before the valve and spring so you are correct.

On the picture Don posted, the washer or seal, appears to be part of the valve.
