Mr L.
The old girl deserves some miles. But what about the car?

It does sound as if the obscure cause of your brake problem has been found. I hope so.
Have you spoken with the garage by whom the servo master cylinder were fitted?
I don't have a chronology of your various garages and what they did re the brakes. I am wondering.
- How did the error occur? Did the items arrive separately or conjoined? Was information available to that garage as to adjusting the pin? Is that a standard issue re servo and master cylinder in other cars?
- Re intermediate garage(s). Is that servo/master cylinder interaction part of a routine thorough checking procedure that they should have found the problem?
- Re your new Best Friend For Ever garage. Have they told you how they found it? Was it suspecting the master cylinder and happening upon the wrongly adjusted pin?
Interesting that a brake bleeding problem appears to be a servo/master cylinder fitting problem.
