With the car turned off for several hours the fluid returns to the reservoir (from level mark to completely full) and turning ignition on takes 30 secs before ABS pump cuts off.
Once upto pressure with ignition on, depressing brake pedal a few times the pump responds quickly so don't suspect pump. No fluid leaks anywhere. - I think accumulator or check valve leaking.
Any ideas ???

I can't help you ... BUT... Just to clarify your Q ...

Mike,
The reservoir has min & max level mark (only 10mm difference) when system is upto pressure the level sits between the marks after several hours the reservoir is completely full to filling cap. If the ignition is switched on and ABS pumps for 30sec level returns to between the max/min marks

If you are only getting 2 pumps from the brake pedal and then the pump runs, suspect the accumulator is weak.
