Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) Brake booster - 1970s - does anyone recognise it

I have the following brake booster on my 1977 plus 8:



Does anyone recognise what part number this is? I'm guessing it is a Girling part, maybe. I don't see an obvious equivalent part on the usual websites (Melvyn, Gomog, BH).

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...

I think it may be this part:

https://rimmerbros.com/Item--i-GSM125P--SelectedCurrency-1. equivalent to https://rimmerbros.com/Item--i-GSM125. which appears to be an MGB servo and is a Lockheed part.

Up to 1976, MGBs had single circuit brakes with a remote servo just like that. Lockheed.

Dave, do you need a complete unit, just parts, or a re-sleeve ?

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. The community now takes its lead from cars that are nothing like what we have.

Hopefully, I don't need anything currently - but this car is new to me, and I've never had a Morgan with a brake servo before - so just trying to learn the system, just in case. Forewarned is fore arrmed as they say.



- that could well be - I only have the history of the car back to the mid-90s so I'm unsure of the original configuration- I've contacted the factory in the hope they may be able to shed some light. There seem to have been quite a few mods to the car over the years....


Curiously, I had a chrome bumper MGBT in the 80s that must have had that servo on it, but I have no recollection of it (ie the servo) at all. One of many cars I wish I'd kept....

Many thanks, all.....
