The strings would only work if you could isolate airflow through the 1 x 6 opening. Any other air flow (such as if the vehicle is moving) will give false readings; any body movement (without air flow) may give false readings. But!...there is almost definitely air movement at the rear brake during a race without the scoops, therefore, the combined effect must be measured. I'm thinking the only way you can measure the effectiveness/need of the rear brake cooling devices is to attach to the caliper an electric pyrometer used for diesel EGT that saves the peak reading. The readings would need to be taken after a full race as the heat buildup is cumulative (one lap is not enough). Lemme see if I can find any EGT setup that would work in this application...

As I keyed the above I was thinking, "EGT is not going to work here." Then I found this:



High Temperature Infrared Temperature Sensor

These temperature sensors cover ranges up to 1200 Deg.C. The housing is manufactured from aluminium and is supplied in anodised red. This sensor is especially suitable for brake temperature measurement.
