inward causing the spring to contract in its housing, allowing the motor to rotate the modulator gear. The most common application of this
principle is in window crank mechanisms, where a small amount of force on the crank handle allows the window to be lowered or raised, but the
weight of the window or force on the window will not allow the window to move downward. For the ESB, brake pressure on the top of the pistons
corresponds to the weight of the window and the motor corresponds to the window crank handle.
