Two brake modules use air-actuated cylinders to press performance brake pads onto the aluminum rail that runs the length of the tube. The brakes provide a combined 4-ton clamping force, safely decelerating the pod to a stop. A precision linkage and elastic shock cords suspend each brake from the rest of the vehicle so as to isolate the pod from impulses from the rail. Pressure transducers, thermocouples, and proximity sensors allow the pod to monitor braking pressure, pad temperature, and pad extension in real time.
