As 95Badboy said...you need to get hold of a voltmeter.
Turn on the ignition and jam the brake pedal down with a lenght of timber then measure at the brake light for voltage.
First measure between the connection on the bulb itself and the ground on the bulb itself....if you have 12 volts there then your bulbs are blown or you have dirty contacts inside the bulb holder.
Now measure between the connection on the bulb and the other meter lead going to the chassis somewhere....if you now have voltage it means the grounding to the bulb holders is gone which is a common problem.
If you do not have voltage at the rear at all then you need to start measuring the voltage at the brake switch.
Does the third brake light work? If not then you probably are losing voltage right up front near the brake switch.
Once you have a multimeter to fault find....even a cheap one....the rest is not rocket science!
