BTV power piston help required.

Hi,

Does anybody know where I can obtain a replacement, NOS or overhauled power piston assembly for the BTV as fitted to a 1955 400 or maybe a replacement poppet valve and diaphragm kit.
I recently overhauled my BTV with a kit from Max due to loss of braking efficiency and discovered fluid had leaked into the power section and has contaminated the power piston diaphragm and the internal poppet valves are also worn. The overhaul kit did not include these parts for the power piston only the leather outer seal and cord which I have replaced.
The hydraulic section was fully overhauled and is now fine but the power section is not working properly, I am aware of the downfalls of the BTV system and would replace it with something more modern if a direct bolt in replacement kit were available, however I currently don't have the resources or time to try and adapt something else to fit so I am stuck with having to repair what I have for now.
Any help or links to a supplier for these parts would be appreciated.

Regards,

Dave.
