It's actually a portion of the combo valve that's giving you grief now. There is a shuttle valve that shifts to stop leaks from causing brake failure and when shifted will also turn on the dash light.
You can try stomping the brake pedal hard a few times to see if that will equalize the system and shift it back where it belongs and if not, then you need to disassemble, clean it out with some brake parts cleaner and then reassemble it using some clean brake fluid as assembly lube.
Before you install it though, you need to flush the system to make sure that the sediment that fouled the combo valve is all gone.
If that doesn't fix it, post back up and we'll try something else.
