Good day, I have a 07 Town & Country Limited with 115k. I had a intermediate issue of the dash brake light coming on which has turned to a permanent brake dash light on. The reservoir is full, the parking brake is not on (I engaged and disengaged it several times to see if that was the issue), I did a brake booster test ( foot on brake while starting and the pedal moves). I pulled all the tires and saw no leaks and the pads are in great shape. There is vacuum when I pull the line from the booster from the engine. I see no leaks at the master cylinder or anywhere else. When I stop on the brake pedal it goes down but does not continue to fade so it appears the master cylinder is OK. The one thing I noticed is this. If I hit the brakes very had several times and then shut the car off and then on, the light goes out. After I drive it a few feet the light comes back on again. Any help would be greatly appreciated. Ps. Not that it may matter, I flushed the lines with new fluid yesterday as the fluid was very dark. It did not help, as expected.

 

I found them useful and repaired mine sensor with 10k 5% resistor. Inside that sensor is only reed switch and parallel 10k resistor, molded in plastic.
