My owner's manual says it's either low brake fluid or a faulty parking brake switch.
The brake light on most vehicles is not only an indicator that the parking brake is on, but that there is a problem with the system.
it may be because there is another problem in the brake system
You might have an ABS problem or a problem with the brake master cylinder. Check the fluid level in the brake reservoir.
The parking brake is set by pushing, with your foot, the parking brake pedal on the left side of floor area. It is released by pushing with foot again.
the parking brake on caterpillar dump truck is spring applied and pressure released
Because the e brake is hooked into your braking system and that system has a problem.
The engine does not have to be running to release the parking brake on your 1994 Cadillac Seville. The parking brake can be engaged or released without the engine running.
If your parking lights are on and your left brake light doesn't work, the brake may have burnt out. You might also have a wiring problem.
It means that your parking brake is on. :-) Or there is a problem with the brake system, as in low brake fluid.
the parking brake is either sticking or the sensor is bad This could also be a warning that there is something wrong with the braking system. The light is not only for the parking brake in most vehicles.
Make sure the parking brake is completely released. If the parking brake is on the Highlights go off.
either your parking brake is not released all the way or the switch needs adjusting
