Hi Gaz

Sorry I didn't reply to your PM been busy,

Above suggestions are correct just use a remote servo one in each brake line.

I personally wouldn't use the Lockheed one as it has to be mounted I a particular way to work which can limit mounting positions.

I was looking at this one as its a duel circuit and compact.
