The brake light stays on after a rear brake job was done and the front wheel bearings were replaced. The shoes, cylinders, springs were replaced and drums were turned and the lines were bleed. In the process of diagnosing the problem the e-brake pedal would go to the floor, so I rechecked the e-brake cable and corrected the rear e-brake cable to arm connection on the back shoes. This corrected the pedal issue, but not the light. All the brakes are working properly. I also refill the brake reservoir, but the light is still on. I checked the switch on the e-brake pedal and it has 0.0 volts when the pedal is up and 7.5 volts when the pedal is depressed. What other sensors activate the e-brake light? Does the anti-lock brake system activate this light, too? What should be my next step?

unplug the sensor at the master cylinder. usually when they go low, they will stick when you refill them, try tapping on sensor if that puts the light out

Thank you for the quick reply. While you were posting I was checking the reservoir sensor. I checked for leaks and fluid level. Since the reservoir was filled to the brim with the extended fill spout the level was hard to determine and fluid had coated the outside of the reservoir. I tapped the reservoir side to see how much fluid was there and jiggled the sensor connection. The light went off!!!!

It must have been a stuck float.

Thanks for the confirmation of the problem. If the light goes on again I feel confident that it might be the connection or wiring problem, but at least the problem has been localized. ;-)
