Notes: This is a single-circuit brake system, the red arrow is the line coming from the brake master cylinder and the green arrow is the line that goes off to the 4-way junction with the brake light switch.
Many thanks...

You missed it. https://www.gomog.com/allmorgan/brakeservo.html

I do not have much posted It is odd that you have one. Must have been a requested option by the first owner. AFAIK, at the time they were fit as standard to only the US and Swiss Plus 8s, otherwise optional in Europe.

I can get more info if you need it. Porbvably have a diagram in archives. I also know mogs fit with them. BTW, most people removed them, https://www.gomog.com/panel/response20.htm but I cannot, at this time, recommend anything better aside from the Caparo units which corrected the unhappy brake proportioning on the 1977 to June 1993 Morgans. Until recently, mogs have been so light they did not need much in the way of braking, despite all the fuss we make about brakes. smile The community now takes its lead from cars that are nothing like what we have. wink
