  2. Background • Use of Carbon-Carbon composites in place of steel rotors and organic composite pads • Will result in improvements in scoring during the competition at FSAE events • Higher friction coefficient • Results in better lap times due to late braking • Less frequent maintenance • Higher strength pertaining to forces that will be applied results in less frequent rotor replacement

  3. System Components

  4. Brake Pedal System • Will withstand 2000N of force for safety • Sliding rack assembly for ease of position change for ergonomics • Will use at least a 3:1 mechanical advantage • Allows for ease of input effort will maximizing output force • Will be made with steel materials • Allow for the safety factor

  5. Master Cylinders • Use of two master cylinders • Allow for greater and more finely tuned front to rear bias adjustments • Two different sizes will allow the front to be biased without effecting brake pressure in the rear • Each master cylinder will have an independent reservoir • This will allow for bleeding of front or rear brakes individually if needed

  6. Brake Lines • Custom fitted lines • Will allow for the atypical packaging that will be used to retain ergonomics • Braided Steel and Steel Hard Lines • Braided will allow for some flex in certain areas while remaining rigid enough to avoid flex • Line Shielding • Any areas that has a brake line exposed to a moving mechanical component will be shielded to avoid brake line failure in the case of a component failure

  7. Calipers • Wilwood PS-1 • Calipers will be utilized from Wilwood due to their reduced weight • Calipers will also fit within the dimensions of the custom rotors and uprights • Most cost effective since outsourced

  8. Brake Pads • Will be made out of Carbon-Carbon composite • Will test three different composites • Diamond, Silicon Impregnated, and Treated Carbon-Carbon composites • Backing plate will not be utilized • This will allow for a faster manufacturing process with minimal excess material • Minimizes heat transfer between the pad and surrounding areas

  9. Rotors • Silicon Impregnated Carbon-Carbon • Allow for a higher friction rotor • Reduces un-sprung weight • Better wear resistance when compared to typical steel rotor • Pedal Feel • The pedal feel that the driver receives will be more consistent due to Carbon-Carbon’s temperature resistance

  10. Sensors • Thermal Infrared • Allows the collection of data that will allow comparisons of behaviors at different temperatures • Brake Failure Switch • Activation of a over travel switch will trigger the brake system to lock all four tires for a safe stop in case of component failure • Brake Line Pressure Gauge • Relay to the driver that the brake system is operating correctly • Allow for fine tuning of brake pressure for bias
