* brake switch mounted on the brake pedal
Follow the stem of the pedal up to where it connects up under the dash board. when you press on the pedal with your hand, you'll see a switch let out. There is two switches if you have cruise control. It's a 25 cent switch that ford probably charges five bucks for. It may be hanging up from dirt getting on it from a muddy shoe. All the switches in my 1998 are pretty cheap and hang up often. Spray a little WD40 on it while pushing down on the pedal with your hand. Then push the pedal with your foot and see if it works. Also, check to make sure mounting bracket not out of line from getting hit by foot. If it is, kick it with the other foot.... Watch that little floor light bulb, it gets hot, and smarts when it touches back of forarm. Also, keep WD 40 from getting on bulb. May get stinky when bulb heats up, and it somewhat flammible, but mostly needs a open flame before it lights. Good for frying Spiders in the garage, ants don't like it much either.

Brake lights and turn signals are on a separate circuit from the tail lights. Tail lights are on the same circuit with the dashboard lights. If the dashboard lights aren't working either, check the fuse. If they ARE working, check the headlight switch.
my 98 suburban did the same thing. when i changed my headlight switch that turns them off and on, they started working again.
Replace brake light switch.
The brake lights in your 1983 Nissan pickup truck are controlled by the brake light relay switch. When the brake light relay switch malfunctions the brake lights will stop working.
No brake lights but turn signals work? Turn signal switch brakes route through it.
If none of the brake lights are working i would suspect the brake switch at the brake pedal.
Possible bad switch on the brake pedal? When you push on the brake pedal, it activates a switch, that switch turns on your brake lights. If the bulbs and fuses are ok, check the switch with an ohmeter.
The brake lights and signal lights are tied together in the signal switch, also known as the "multifunction switch".
probably the brake light switch on the pedal if none are working at all
try the brake switch on the back of the brake pedal
brake lite switch will keep it in park
If the fuses and bulbs are okay I would blame the signal switch assembly. They call it a multi-function switch these days.
