The brake light will not turn off even if the keys are out of the ignition.

ON SOME VEHICLES (SUCH AS MY '77 CJ 5 JEEP) THE DARN SWITCH AT THE UPPER END OF THE PEDAL WOULD GET LOOSE--THE SWITCH REMAINED "SPRUNG OUT"...BRAKE LIGHT WOULD REMAIN ON

I DON'T KNOW YOUR VEHICLE BUT THIS IS YOUR SWITCH---MUCH LIKE MY JEEP CJ!

I HAVE SEEN THE SWITCH ON OTHER CARS BEING "JUST FINE" (LOCATED AT THE TOP OF YOUR PEDAL ARM)

......BUT!!!...A LITTLE RUBBER OR PLASTIC CAP THAT ACTUALLY CONTACTS THE "PLUNGER" HAS FALLEN OR ROTTED OFF---NOW THE PLUNGER REMAINS SPRUNG OUT TOO, WHEN THE PEDAL IS RELEASED

A BIG OLE HAND MIRROR AND A GOOD FLASHLIGHT MAY AID IN SEEING THE SITUATION, THUS KEEPING YOU FROM "CONTORTING", UNTIL YOU MUST!

IT MAY HAVE FALLEN IN YOUR FLOORBOARD, OR YOU MAY HAVE UNKNOWINGLY THROWN IT AWAY.

YOU CAN "IMPROVISE" ONE OF YOU CANNOT FIND A REAL REPLACEMENT---A BIG HARDWARE STORE EMPLOYEE MIGHT FIND YOU JUST THE THING!...MAYBE A CABINET SCREW COVER...A KITCHEN SINK CLIP PROTECTIVE SCREW COVER...ETC

KEEP ME POSTED IN HOW IT'S GOING

The stopper is plugged in. Start engine with transmission in P handbrakes applied. Depress the brake pedal to gain access for space to push the stopper in. A little lubricant would make the job easier.
