Are your #brake #warning #lights flashing on and off while you're #driving? If so, do you know exactly what they mean? There are several possible causes if your #brake #warning #light is always flashing repeatedly.  One possibility is that you forgot to release the #parking or #emergency #brake.  Note that the #brake #warning #light remains on when the brake is set as a reminder.  So when your warning light remains lit even when you release the parking brake, then it is a sign of a more serious problem. In other cases, when the #brake #warning #light turns on even when you apply the brakes, or just flashes or is turned on constantly.  This can mean that your hydraulic pressure has been lost in one side of the brake system or it could also be that the level of the fluids in the master cylinder needs to be checked.  If the fluid is running on dangerously low levels, this can mean that there is a leak somewhere in the brake system.  In both these cases, you should carefully check the fluid levels in the master cylinder.  If you simply add enough brake fluid to the reservoir of the master cylinder, this may temporarily solve the problem.  However, if there is presence of a leak, despite frequent refills, all will soon be lost, and when this happens, the warning light will turn on again.   brakemaster4551
