Rear brakes sticking lightly & Brake light comes on and off

[Ccmano]

When you look under the car just forward of the diff you'll see the cable for the emergency brake running cross the car. Follow the cable to the passenger side and you'll see a bracket that mounts it with a single bolt to the frame just ahead of the rear wheel. Undo that bolt completely and let the cable droop. This will take the emergency brake out of the equation. If the brakes still stick it either the master or something in the ABS system. Since you didn't get an ABS warning light its likely the master.
