FSAE Saluki Racing Brake system Team 28 DESIGN REVIEW Saluki Engineering Company Team Members: Preston Lapping(PM); Larry Groth III; Gerard Ketuma; Kevin Trandel; Quo Qian, Khor; Kok Seng, Au Yong Faculty Technical Advisor: Tod Policandriotes

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

System Components

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

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

Brake Lines Custom fitted lines Braided Steel and Steel Hard 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

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

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

Rotors Silicon Impregnated Carbon-Carbon Pedal Feel 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

Sensors Thermal Infrared Brake Failure Switch 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
