There is no button or black cap on my proportioning valve. It's solid with the only connections being fluid lines to the master cylinder and the brakes.
However, while looking for the button you describe, I noticed that the sensor wire was pinched between the master cylinder and the firewall. I loosened it up, got the wire out, and, Voila! Brake light is out!
Thanks to all for your help!
