You will need a volt meter to help trouble shoot. Check for 12volts and ground continuity. If switch at brake pedal is working ok, and fuse ok, check at the rear bulb assembly for volts and good ground and for good connections and check for burnt socket. Burnt sockets can be repaired using a soldering iron and creativity. Heheh.... If ground is missing, look for black wire screwed to the chassis, located rear driver side behind or under the bulb assembly

Does one side work and the other one not? If so the bulb may not be making good contact in it's socket. If neither side works it may be the switch on the brake pedal.
