Hi Gary
Have you had any feedback on this matter yet?
I basically just ate my losses on this. I sent the servo to a place in California to have it "re-rebuilt" and I got it back in about 1 1/2 weeks and it now works perfectly.
The place in California had some colorful commentary on what they found inside!
Was the place in California, PowerBrake as Nick suggested?
I'll need to have my Servo rebuilt, and pleased to see they have a location here in Southern California. If so, I'll get my Servo over there right away.

Please share! The original offender is the most likely restorer that people will come across here, it would be good to hear what these other guys found.
Agree with Mark,
I have mine boxed up along with brake callipers ready to go to said outfit but holding back.
any other suggestions for servo refurbishment as a second option?

Luis basically confirmed my observations on the state of the control valve bore having not been honed so it compromised the seal in that circuit. He also found that the pushrod was actually bent so that was the primary culprit for the master cyl side leak. No sleeving was necessary however he said if they had simply tested their work they would have immediately detected these issues.
Luis just spent some time straightening the original pushrod and working on the air control valve circuit along with a new air control valve seal and a new vacuum diaphragm.
He did praise the plating job that was done by the other firm so all was not lost I guess!
Forgot to mention, PowerBrake did the job very quickly and initially quoted me something like $250 but charged me only $180...
Not really an option for guys outside of NA but I was impressed by them.
Apologies for re-visiting this thread but if anyone is interested I now have more of the stainless steel pushrods available. £15 each. Essential if rebuilding Cooper S servos.

Thanks for the Servo Rods Nick
They are exactly the same as original ( except yours are Stainless Steel )
Using the Lockheed 5 1/2" Service Manual in the Technical section I notice that the spacers are not the same as is, in the Manual (pg9 no 34 )
I have taken 2 apart and both piston rods seem to have corroded in the same places, so the stainless steel ones should sort that problem out.
Thanks again Nick
