Take a screwdriver handle and rap on the side of the master cylinder. Sometimes when you run the fluid real low, the float will stick at the bottom. It can also be the parking brake partially on, air still in the system or a problem with the rear wheel ABS system with a stored code.Try unplugging the big flat ABS module to eliminate that.

John; Did the (I hope NEW) master cylinder come with the fluid level sensor? Is it plugged in?

John; For some unknown reason, my parts illuminator is out to lunch, right now. Thinking back, I'm not so sure those had a level sensor? May have steered you wrong? '92 with ABS? Could you verify the production date? Should be on a sticker on the driver's door.

As I stated in my first response, your truck likely has rear wheel ABS and when it stores a trouble code, it puts that light on. Unplugging the module will put it out.

If it has it, there will be a flat module, probably mounted vertically, right near the master cylinder with one long plug.
