    Sorry for my ignorance but does the FJ60 master have 4 wheel disk or 2 wheel disk?

    This is more of a trial and error thing but most certainly, the fixed porportioning valve you have won't have the correct porportioning.

    Go to www.summitracing.com and order an adjustable porportioning valve for $40-50. and put that in instead of the fixed one. There is a chance you might need to use both but probably not.

    60 master is front disc only. You'll need to pull the residual valve from the rear circuit, remove the factory prop valve, and install a Summit or other adjustable one to balance the system.
