Why three reservoirs?

[Jim Schenck]

The redundancy with the balance bar is similiar to that of a tandem master cylinder in that whichever end has has the failure must be fully compressed before the remaining side will begin to get pressure. This results in a lower pedal height for sure, but still enough travel to get the car stopped. In fact the balance bar often will bind before allowing full compression of either cylinder making it work even a little before the faulty side bottoms out completely. (This is what makes it tough to bleed the system without cracking a front and rear at the same time)

To the original point though, I don't see how having two seperate reservoirs would have any bearing on how the mechanical part of the system functions? If the issue is you are not comfortable with the function of the balance bar that is a completely seperate from saying it needs a whole second reservoir to be able to perform a single emergency stop. How would having an additional reservoir have any affect on stopping if the balance bar can't push the second master cylinder?

Ding, ding, ding! Thanks for bringing logic to the conversation Jim
