1. An apparatus configured to provide brake signaling to an automotive simulator, the apparatus comprising:
(i) a master cylinder chamber, (ii) a slave cylinder chamber, and (iii) an opening disposed between the master cylinder chamber and the slave cylinder chamber, the opening configured to provide fluid communication between the master cylinder chamber and the slave cylinder chamber;
a master piston at least partially disposed within the master cylinder chamber, the master piston configured to pressurize fluid in the master cylinder chamber when a brake pedal is depressed;
a slave piston at least partially disposed within the slave cylinder chamber;
a pressure sensor disposed to generate a signal representative of an amount of pressure applied and send a signal to a processor;
a dampener positioned coaxially to the slave cylinder chamber to provide an amount of resistance to master piston movement when the master piston is depressed, the dampener including a mechanical adjustment to limit the amount of resistance; and
wherein the dampener is configured to limit axial movement of the slave piston from a first slave position to a second slave position via connection with the slave piston; and
wherein, when pressurizing fluid in the master cylinder chamber, the master piston is configured to drive fluid from the master cylinder chamber to the slave cylinder chamber via the at least one opening to increase pressure in the slave cylinder chamber.
