defintely not a good idea
it the driver brakes for say 30 sec for some reason ( sudden obstuction,i
 traffici pile up etc.) and you geta 30s squirt after there would probably
be water running all over the tires, affecting traction

better might be to use an IR sensor to measure berrake temp. placed just
before the squirt zone, spray until the sensor say the temp is OK again
no timer involved
just a simple driver to fire the pump up
