2002 ford ranger, 3.0 V6 2wd, emergency brake light came on during acceleration and goes away during deceleration or release of throttle on harder acceleration. It will also go away if I stop at railroad tracks and go over them.

I am kinda stumped on this one so any help would be greatly appreciated

 

On the brake master cylinder there is an electrical connector, it is for brake fluid level, if fluid is low brake light will come on.
Check level and also the connector itself

There is also a switch on the E-brake pedal, it works like the main brake pedal switch, meaning when brake is OFF switch is pushed in and brake light is OFF, so if the switch gets loose it can turn on brake light on bumps or motion.
