Parking Break light is staying on????

[HumminNBoatin']

Usually it means its time for new breaks? Right? I added more break fluid to the resevior but that did not put it out. the truck has been sitting allot and that dash light is causing a drain on the battery? Anyone have any suggestions? I do know the pads are ending their usable life but... They still have probubly 5-10K miles on them and I dont want to change them untill spring unless I absolutly have to.
