===Brakes===
Brakes on a race car are imperative in slowing and stopping the car at precise times and wear quickly depending on the road or track on which the car is being raced, how many laps are being run, track conditions due to weather, and how many caution runs require more braking. There are three variables to consider in racing: brake pedal displacement, brake pedal force, and vehicle deceleration.<ref name="Groot, S. 2011">de Groot, S., et al. "Car Racing In A Simulator: Validation And Assessment Of Brake Pedal Stiffness." Presence: Teleoperators & Virtual Environments 20.1 (2011): 47–61. Academic Search Complete. Web. 7 Dec. 2016.</ref> Various combinations of these variables work together to determine the stiffness, sensitivity, and pedal force of the brakes. When using the brakes effectively, the driver must go through a buildup phase and end with a modulating phase. These phases include attaining maximum deceleration and modulating the brake pressure.<ref name="Groot, S. 2011"/> Brake performance is measured in bite and consistency. Bite happens when the driver first applies the brakes and they have not warmed up to the correct temperature to operate efficiently. Consistency is measured in how consistent the friction is during the entire time of braking. These two measurements determine the wear of the brakes.<ref name="Groot, S. 2011"/>
