Sorry, but that's backwards. You're right in that if the pistons were
the same size, the force would be equal. But, if the area of the slave
is 1/2 the area of the master, then it exerts only 1/2 the force applied
to the master.
The hydraulic pressure is the same everywhere in the system. If the
pressure is 100 pounds per square inch, and the piston area is two
square inches, then the force on the piston is 200 pounds. If the
piston area is only 1 si, then the force is only 100 pounds.
