MG MGA - Mounting a servo

Having bought a brake servo, I am now at a loss as to where on the car to mount the devil. I have read other threads from people fitting a servo, there are various ideas as to where to mount it, but the one that appeals to me is behind the front RH splash plate. I shall be extremely grateful if someone on this forum would be kind enough to give me a short but clear explanation on how exactly to mount the servo under the RHF wing. Pictures will surely help of course. Many thanks.

It's all documented on Barney's site.

Frank, I sent a picture showing how I mounted mine in that position to your last thread. Did it not appear? regards David

Barney's site shows what I have done plus I added a cruise control because of the vacuum was there. If you have any questions, let me know.

Hi David Jacobs:

sorry I have not seen any pics coming from you. Would you mind if you send it again. On second thoughts you can also send the pic as an attachment to an email. My email address is shown on the top of my email. Many thanks.

Hi Jeff Becker,

as a matter of fact I am currently trying to copy what you did, but I am finding it difficult to follow how you did it. Don't wish to put you through any trouble, but a short, but clear explanation will be of great help.

Thanks Jeff

Hi Frank,
Lets see if I can explain it. I went to a tin shop who made a platform for the booster,cruise control and the extra vacuum reservoir to sit on and mount to. I pre-drilled the holes in the body with a angle drill. The platform had about 2-3 inches that was bent at the top and bottom to mount to the body. I assembled the booster,cruise and vacuum with the platform out of the car. I used screws to hold things together as in the future I would have to remove it for repairs. The tin platform was riveted to the body. My car is a left hand drive so I have a rod that goes from the gas pedal to the passenger side and then thru the firewall. I hooked up all linkage to run to the rod on the passenger side. There are no cables that can be seen. The booster is hidden and so are the cables. I drilled a small hole in the back of the intake manifold to acquire the vacuum that is needed. The end piece is like a water plug on the side of the engine. In the future if is unwanted, it can be reversed with a new plug. The vacuum was built by a hot rod shop who makes hoses. I took a coat hanger and bent it to the shape I needed the new vacuum to fit in the car. Off the back of the intake manifold an adapter was fitted into the manifold and a 6 inch flex hose then went to the s/s steel vacuum line. The s/s line went on the lower bulk head just above the trans tunnel. On the side wall inside the engine three hole were drilled, one for the vacuum line and two for the brake lines. When everything is installed, the only thing that is visible is the vacuum line at the back of the bulk head. I hope this helps you and if you have any specific questions, I will see how I can help.

Hi Jeff,

thank you very much for such a detailed explanation. I have just went through reading it, but right now I don't have the time to read it slowly step by step. I will read it slowly and see if I can follow the instructions. If I find it too complicated I may come back to you for help. If you have a photo available please let me see it too.

I'm uneducated about servos but interested. Does the servo have a seperate fluid reservoir, or is it somehow fed from the master cylinder?
In the m/c the washer is configured so that it can "pump up". Is the slave side of the servo also configured this way?
Art Pearse

Fluid goes from the master cylinder, through the remote servo, and on to the brakes as a single circuit. The servo does not have a separate reservoir (but it may sometimes be a problem to bleed).

Hi Frank,
The picture of my unit is on Barney's site. Let me know if you need any other information.

My thanks go to Jeff Becker for his advice and assistance. Jeff I shall have a good look on Barney's site. As a matter of fact I have finally grasped the way of mounting the unit, and after producing a cardboard template I am now in the process of fabricating the necessary bits and pieces required for the job. The large mounting plate that comes with the unit is about to be bent and twisted to meet my requirements. At the moment I have put the job on hold, simply because the heat in my garage is unbearable. Will finish this project on the change to cooler temperatures. I was also thinking of buying a domestic air conditioner, but at my age now it is a waste of money. I seldom do any work inside my garage these days, I am now completely retired.
