I understand the basic principles of a floating caliper. The piston pushes against the pad which contacts the rotor. Simple! But how does the other break pad on the opposite side make contact with the rotor?How is it "pushed" in the opposite direction? What are the fluid dynamics that cause the caliper to move in the opposite direction of the piston?

Single Piston Floating Calipers are the most popular and also least costly to manufacture and service. A floating caliper "floats" or moves in a track in its support so that it can center itself over the rotor. As you apply brake pressure, the hydraulic fluid pushes in two directions. It forces the piston against the inner pad, which in turn pushes against the rotor. It also pushes the caliper in the opposite direction against the outer pad, pressing it against the other side of the rotor. Floating calipers are also available on some vehicles with two pistons mounted on the same side. Two piston floating calipers are found on more expensive cars and can provide an improved braking "feel".

Yes, but "how" exactly does it push the caliper in the opposite direction?

The floating caliper has to have slide bolts and the caliper actually has to go back and forth on the assembly with the bolts sliding back and forth. This forces one side of the caliper in and it draws the other side out. That compresses both sides at the same time with one piston.....hope this clears things up a bit for you...
