This has been happening a lot lately, I've started my car up in the morning and i put the car into drive (yes i have auto please nobody grill me

) but i put the E-brake down but the red "brake" light still remains on. Should this even be a problem or what, im confused?? Plus iit'll finally go off for like 10 seconds then pop back on. It doesnt happen everytime but its happened a few times this past week...help!!
