Check your brake pedal, follow it up into the under dash. You should see where the pedal stop meets a bar with a switch attached. The rubber piece that triggers the swith to shut off the light when the brake is released probably broke off which leaves a hole in the pedal bar for the button on the switch to go through without being depressed to shut off the light.
There's a switch that the brake pedal engages when pressed that makes the brake lights go on. this switch may be stuck.Or the peddle staying on switch
Any sudden brake loss can be the cause of 1. brake line damage 2. master cylinder disfunction
i would try changing your bulb in the rear of the car first then if it still not working then look for fuse or wiring problem
These lights are probably all related. When there is a problem in the ABS system, this will disable the TRACTION system, which will inturn illumiinate the Service Vehicle Soon light. A common cause for this is there is a problem in the ABS. A faulty wheel speed senor or the harness to the sensor may be faulty. When the ABS computer (EBCM) sees a problem in the ABS, it can cause all these lights to come on. A scan of the ABS computer would be the first thing needed. Then, diagnosis of the system / circuit that is at fault would be needed. Tech JK -----------------------------------------------
Sounds like bulbs need to be replaced--they most likely are double filamented-larger filament for tail lights and smaller for brake lights be a broken wire or a bad ground Depends on the car....most use 2 different circuits the top light going straight to the brake pedale switch and the tailights going through a control module THEN to the tailights. Check EVERY fuse you have in the car
you may want to make sure you have a DUAL(meaning TWO pieces of wire inside the bulb) filament bulb on the brake lights, if you just replaced the bulb and used a MONO filament bulb it will cause this to happen. If this isn't the case, you may want to take it to a mechanic to make sure the sensor that senses when you are pushing the pedal isn't stuck or out that would also cause the same problem.
brake light switch would be most common cause
fuse, bulbs
Possible ground issue at the taillights.
BAD BRAKE LIGHT SWITCH AT TOP OF BRAKE PEDAL
a bad or mis-adjusted brake switch.gmjim
The BOO (Brake On/Off) Switch may need to be replaced. If it is bad, it would cause the brake lights to NOT illuminate when the brake pedal is applied.
More than likely it is the brake light switch that is attached to the brake pedal.
Check your brake light switch at hte brake pedal.
brake switch located on the top of the brake pedal
if you recenly replaced bulbs u may have installed them backwards they should be running lights and brake lights if this is the case they maybe installed incorrectly
The most likely cause is a bad brake light switch (if none of the brake lights illuminate) but if its only one of the brake lights, try changing the bulb. Even if they still work as running or turn lights because they have a double filament and may still work partially, but not as brake lights.
Check the switch adjustment on the brake pedal arm.
