Jim,
You raise an interesting question. I was trying to think my way through the idea that the spring on the drive arm had the same effect as a spring on the pedal, in as much as, the spring on the drive arm is placing a positive pressure on the rod arm in the direction of the cylinder return. Is my thinking skewed on this line? I will note the travel on the pedal now that you raise this question, because I can also visualize that if the pedal does not fully retract that it would create the situation that you suggest by not fully activating the internal valve, which creates a resetting type motion for the slave. I do not know how the slave works to this end, as I thought it was a simple motion of the plunger traveling through the cylinder with the application of pressure from the pedal and returning as pressure is relieved. Can you sort through my reasoning and set me straight?
Fred
