Tod Policandriotes

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

Background

System Components

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

Brake Pedal System

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

Master Cylinders

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

Brake Lines

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

Calipers

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

Brake Pads

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

Rotors

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

Sensors
