You never get less movement.  You get slower movement, more fluid 
flow, and longer pedal travel until the shoes move the same distance 
to come into contact with the drum.  When it stops moving you get 
higher force from the hydraulic pressure on the larger piston.  Ergo, 
more braking force on the rear wheels and possible rear wheel lockup 
(after longer pedal travel).
