Brake light on Dodge Caravan

My wife has a 2001 Dodge Caravan with 133,000 miles on it. Several weeks ago, the brake light started coming on whenever the brakes were applied. However it does not do it all the time. I checked the fluid and it is full and I have not seen any leaks in any of the lines. Also the brake pedal is fine, no sponginess or anything like that. The front pads and rotors were replaced 15,000 miles ago, but I have not had a chance to do the back brakes yet. I should note that once you start driving from a stop, the light goes out. I am not sure what else to check. Thanks.

I would check the owner’s manual to determine what the brake light on your Dodge means. I would not put this off. Suddenly not having brakes is not a fun thing. Trust me. I was on my way to the shop to have them fixed, when they totally when out.
