In my 1993 Altima, I've had that problem 3 times. Each time, it was the alternator. I used a simple voltmeter check to isolate the problem. Battery voltage should be 12-13 volts without the engine running. When the engine is running, that voltage should increase to 14-16 volts. If the voltage does not increase, your alternator is bad...( NOT! the battery won;t go past 12.6 volts....they dont make them to go that high!}

The Nissan Altima has an opaque cylinder that holds the brake fluid. Looking on the side of the cylinder, check the high and low marks and make sure that the fluid is between the two.
It's probably your Alternator that is going bad. That is if the battery and brake lights came on at the same time.
Any DOT 3 Brake fluid
