It means that there is a problem with the braking system. Have the car looked at by a repairman.
Among the problems that could cause the brake light to display are:
The red brake light on the dash means that the brake fluid is low or the parking brake is on.
your park brakes are on
it needs brake fluid
If you mean the " BRAKE " light in your dash it's just under the " 0 " on your tachometer
Assuming you mean the red " BRAKE " light in your dash is lit : That means that either your BRAKE FLUID LEVEL IS LOW in the brake master cylinder or your parking / emergency brake is engaged
If the brake light in your dash is on , either the BRAKE FLUID LEVEL in the brake master cylinder in your engine compartment is LOW or your parking brake is on
It means that your parking brake is on. :-) Or there is a problem with the brake system, as in low brake fluid.
Either your parking brake is on or the BRAKE FLUID level is LOW in the brake master cylinder
If you mean the red " BRAKE " light in your dash is on , that means that the brake fluid level in the brake master cylinder located in your engine compartment ( on a Ford Taurus ) is LOW ( or that the parking brake is on )
if you mean the brake light on the dash... fill your brake fluid as it's probably low If you mean the brake lights outside the car, your switch is shorted and needs replacement, or you need to lift your foot off the pedal
it means either your emergency brake is on or your low on brake fluid
ABS (Anti-Lock Brake System). If the light is on then you have a problem with that system.
