    Default GS spheres

    I notice that my 1978 gs has 6 spheres, my son's is the same. My 77 club parts car has only 5. All my manuals only show 5. Does anyone know what is going on here?

    From what I recall, a change in ADR's meant that a seperate brake circuit had to be developed, requiring the use of an extra sphere. Your 77 Club parts car is possibly a private import that managed to somehow avoid this regulation. Does it have the warning light above the handbrake?
    My 77 Pallas had the extra sphere.

    Yes it was a temporary safety addition that introduced quite a few idiosyncrases to the hydraulic system. I seem to remember they wouldn't fully depressurize unless you held them up a bit and it was tricky to get the extra accumulator off to check its pressure and then get it to screw back on again. I think there were some one way valves added into the circuit as well. The 5 sphere system was much simpler and thank goodness all the private imports stayed with that system.

    Cheers, Ken

    Thanks guys, maybe I should revert mine to a 5 sphere system.
