Check around brake pedal for something rubbing. If OK, I'd look into the master cylinder.
The brake light switch on a Nissan is located just behind the brake pedal. It sends a signal to the brake lights when the pedal is pressed to turn them on.
nothing it could just be the tail lights coming on.
Brake pads are the pads that sit on top of the rotor that when the brake pedal is pressed the brake pads squeeze the rotor and the car stops. Signs that they need replacing are if you hear squeaking when pressing the brake pedal.
If none of the brake lights are working i would suspect the brake switch at the brake pedal.
probably the brake light switch on the pedal if none are working at all
Sticking Brake LightsI had this very same problem when I owned a Nissan 300zx. There is a switch in front of the brake pedal that when the brake pedal is pressed the metal part of the pedal presses down on a little button which turns the brake lights on when pressing the pedal. What I did was I got under the dash, took a flashlight and put a little piece of tape in between the pedal and the switch. It acted as a cushion because the pedal wasn't pushing down on the switch as it was pushing on the tape and when I pressed on the pedal the lights would come on but the tape pushed the pedal back to shut the switch off. If you want to avoid all this consider having your brake pedal adjusted. If your brake lights come on still consider having your cars wiring checked out.
Probably your emergency brake pedal. Try lifting up on your e brake pedal and see if id goes out.
try the brake switch on the back of the brake pedal
The switch on the brake pedal is disconnected or defective. The shifter interlock has to get a signal from the switch to know the pedal is being pressed before it will release the shifter.
BEHIND THE BRAKE PEDAL
test the booster with engine turned off, pump brake pedal until pedal goes hard then hold foot on brake pedal and start engine. if booster is working, the pedal will go soft as it should for mormal use. if booster is not working ,the pedal will stay hard
