Joe :
It gets confusing here, since there are many different places to measure
pressure.
The force exerted by a hydraulic piston is the hydraulic pressure times
the area of the piston. So, if the system pressure stays the same, a
larger slave piston means more force applied to the shoes.
Perhaps your authority said the _pedal_ pressure (or the hydraulic
pressure), would be higher with a smaller cylinder (for the same braking
force). Or, perhaps he was talking about the master cylinder (where a
smaller piston gives you more braking force for the same pedal
pressure).
