Luis,

There is no brake on an R/C servo.  The servo is designed so that its 
position is dependant upon the pulse width of the controlling input signal. 
If any external force is applied to the servo, the device will automatically 
try to correct the positional error.  If you stop supplying the controlling 
input, the servo will go to sleep after a short period and will allow any 
external force to change its position.  The gearing only makes it a little 
more difficult to move.
