Nope, small syringe is the lever, big syringe would be the pistons. Have you ever realy done any engineering theory? I do know what i am talking about, as does Adam. EDIT: One fairly good example actualy would be between the standard hope mono mini and the mono trials, both brakes use the mini lever, which if i am correct uses a 9mm cylinder, in a standard mono mini the pistons are around 20mm diameter where as in a mono trials they are around 25mm, and we all know which is the more pwerful brake, but as i said earlier, the mono trials, because of this would be slightly more spongey and would require the pads to be closer to the disc to get the same lever movement.
