Start with basic troubleshooting. Remove the offending lamp. When you step on the brake, is there 12V to ground at the lamp socket? Does the "Lamp Out" light come on with the lamp removed? If yes, then the bulb/lamp assembly is at fault.. If not then something upstream is not providing the correct voltage/current to lamp .
Good Luck, Dan
