Do any of the brake lights work either the Left, Right or High Level lights?
If none of them work then the first stage would be to check for coltage at the Lamp Holder of at least one of the Lamps to see if there is Voltage there when pressing the Brake Pedal.
If there is Voltage there then it must be a Bulb Issue. Have you put the correct bulbs in the vehicle?
If there is no voltage at the Lamp Holders then work forward and check the voltage at the Brake Light Switch. If there is Voltage there then the fault lies with either the Switch or the wiring between the switch and the Brake Lamps. The next stafe would be a continuity check between the Brake Lamp Switch and the Lamp Holder. If you have Continuity then the Switch is at fault.
If there is no Voltage at the Brake Light Switch then the next stage is to check the fuse. Has this blown and is there power coming out of the Fuse Box at the correct Terminal.
