I'll assume you mean the warning light in the dash. The most likely reason is that you are low on brake fluid. CHECK IT NOW!!! As well, check for any leaks in the brake lines as the fluid level should not drop low enough to set off the warning light just from worn brake pads. There could be an intermittent short in the system or a problem with the emergency brake switch but the most likely culprit is low brake fluid. So... as I mentioned...CHECK IT NOW!!! Brakes don't work well (or at all) without an adequate supply of brake fluid. And be sure to use the type recommended for your model...using the wrong type fluid can be almost as bad as having a low level over time. And cleaning up the mess caused by using incorrect fluid can get to be a bit pricey. I'll assume you mean the warning light in the dash. The most likely reason is that you are low on brake fluid.

how to change a brake light on 2002 Nissan altima
emergency brake light stays on
The light on the dash that says the emergency brake light is on could have burned out if it does not light up when the emergency brake is actually on. In some vehicles, this light will not light up until the car is put into gear to warn the driver that the emergency brake is still on.
low brake fluid
brake light and battery light is on
my brake light stay on but emergency brake is unhooked
There is an electircal switch that 'senses' when the emergency brake lever is applied and lights a warning light on the dashboard to keep you from driving in this condition. This switch may be faulty or out of adjustment, causing the warning light on the dashboard to turn on.
If the brake fluid level in the brake master cylinder is low ( in your engine compartment ) that will also turn on your emergency brake light just as if the emergency brake was applied
Check the brake fluid level, as on many vehicles the "emergency brake" (in the UK, Hand-brake) warning light also acts as a warning light for low brake-fluid.
on the emergency brake, pull it up one click light will turn off.
It could be something as simple as a faulty or out of adjustment emergency brake switch. If that's not it, it could be the ABS. Often when the ABS fails the computer will turn on the emergency brake light.
Bad switch on the emergency brake handle.
