1964 S brake system fault spoting

[sandman]

Etienne,

I got a NOS kit (that I'm keeping for my own servo) - but I might be able to scan the diagram for you... would that help?

Two other possible causes that I have seen on other peoples cars resulting in the same sympton:

Is the non-return valve operating correctly / fitted in the right way?
Are the hoses to the calipers not twisted?

Evening chaps,

I much appreciate your help, thank you,
hope my brand new braided lines are not twisted, they are home made with a rubber wrap around to keep a period look,
I would rather suspect the non-return valve.

Sandman, I would be much obliged if you could scan your diagram, yes !

hopefuly, I will find some time this WE to have a closer look,
I actually wasn't able to spend some time on the car this last week.

Cheers, Etienne

Also worth checking the right master cylinder pushrod is fitted. I cames across this a year or so ago, the pushrod was too long & sat on the inside of the bulkhead stopping the fluid returning to the reservoir when releasing the brakes. Un-doing the two nuts that hold the cylinder down should be enough to proove if the brakes release & the lights go off.

Mike.

Mike,
It seems you were right,
I first undo the two nuts that hold the master cylinder, and the brakes released ...
I then put two washers between the master cylinder and the bulkhead, tight the whole and had a quick test run.
It was almost perfect, so we used the car to take the kids to the shops
Still, I need to understand if I have the right pushrod, and/or if I need a proper plate to fit in between the cylinder and the bulkhead.
Thank you guys !
