hey guys I need some help. Today I got off of work and my brake light on the instrument panel was on. the e-brake is not engaged, i checked it multiple times. why would that happen and how can i fix it? thanks

 

Low brake fluid most likely. If it is low, check for leaks and pad wear. Typically if the fluid is low in the reservoir, your pads are worn and it may be time for replacement.

 

Indeed, bad alternator will shoot out a brake light as well correct?

 

not sure about the alternator s0ber but the brake fluid i just checked does seem a tad low. and i think my pads are about done also. how long do i have? can i just add fluid until i can get my pads and rotors done?

 

Bad alternator will show brake light and battery light at the same time (well that indicates a charging system fault -> most likely a bad alternator)

 

No way to tell how long you have... it depends on how you drive, etc.

 

actually, it happened to my sentra, my brake light came on, all brakes are fine, e-brake fine, battery light not on...eventually battery light came on when I just had no more juice in it
