Had a conversation with someone about this a while back. How do the rear brakes know they should operate if the anti sink valve is closed?CitroJim wrote:The normal sit in the boot test for the main accumulator works.No, only way to test the Anti-Sink sphere is to have it off and pressure test it... Or a quick test is to see if there is any rear braking available after the engine has been off long enough for the anti-sink valves to operate. The only source of rear brake pressure then is from the Anti-Sink sphere...

On the sphere life front. I had a bit of a job with trying to replace one of the rear spheres on my GSA and decided in the end to keep the 25 year old Pliedies regassed one on. The other side I did replace with a brand new one from Chevronics along with the other 3, the difference in springyness between the two sides is negligable. I believe that ren16tx's GSA is running on spheres that were fitted in the mid 90s. Both his and mine are still softer than my XM with 2 year old spheres and before it's pointed out, the XM is a soft as it should be!
EDIT 2: Actually,I wonder if its something to do with the GSA loosing most of its hydraulic pressure after a few hours?
