i dont get it, after putting on bigger tires and cranking the torsions, my brake light is coming on once i come to a complete stop for the first time when the truck is cold. then when i start moving again, it will turn off after about 1/4 mile. if the truck is warm it doesnt do this, only when i first start driving it that day. it bugging the crap out of me. anyone know why its lighting up?

 

check the brake fluid level.

 

if your fluid level is ok, check the sensor in the cap. Those things are always failing at odd times.

 

+1 thats what mine was
