[urq] Brake servo questions 83 UrQ

[AudiQtroCp at aol.com]

Mike, your 81 which i was interested in most likely has a steel brake servo, 
they are different from the later aluminum ones on our 83's.

That funny bolt is only a set screw, it holds all of the rest of the 
components in to the servo.

Do NOT remove that screw with the master cylinder off the servo, you sill 
likely have the contents of the servo jettisonned into your engine compartment.  
No matter how much you seal that screw it wont solve the problem, its the 5 
o-rings and the seal inside that is letting the fluid leak past TO that screw 
which is not the only place is will be leaking...  There is a recess just ahead 
of that screw where the fluid will also leak thru, although betweeen the 
mascter cylinder and the servo there is another o-ring (not included in the kit) 
which stops a good portion of it.

Good luck, and consider a second set of hands if you decide to tackle the 
project yourself.
