I take it that no-one responded to your first post about this - I'll give it
My gut tells me no. Most problems with re-built Girling boosters seem to
centre around not getting the vaccuum piston aligned correctly, so that it
hangs up, typically not right away, but after the first few brake
applications, sort of cumulatively. The brakes then lock on and won't
release. (Don't ask me how I know about this!) I'm not sure that this
situation can be reliably reproduced off the car - perhaps some other more
knowlegeable lister could chime in here.
In any case, if you decide to mount the servo, make sure you take a 'Genuine
Girling Brake Booster Side-Of-The-Road Escape Kit' with you on the test
drive - consisting of a 7/16" wrench to enable you to let off the hydraulic
pressure at any convenient brake line fitting in the engine bay - in order
to release the locked-on brakes, and a device to plug the vaccuum port on
the inlet manifold after you disconnect the hose so it doesn't happen again
on the way home.
Use caution - you will then have unboosted brakes, and try not to curse too
much as you look forward to the joyful job of removing the booster from the
car once again to troubleshoot. Ugh!

Subject: FW: brake booster test
Anyone know of an off the car test to check if a booster has been rebuilt
properly? I could hook it up to the car engine as a vacuum source or a
Mityvac, but what about the fluid side?
