Repair manual offered me no advice nor did any of the four mechanics I somtimes work with. I checked the fuse, brake lights, control buttons, and even tried swapping out the servo. Any other ideas or troubleshooting procedure would be much appreciated.

does the speedometer work? Is there s pressure switch on the brake master cylinder? the switch could be defective and it's pretty cheap.
