Perform following test:
Engine running idle - steering to right or left full lock 20 seconds - same time pump 
brakes hard 10 to 15 consecutive times - ligth on ? bad belt or  bad pump or bad bomb 
(check valve) pressure bleed before exchange !
Light not on - stop engine - pump brake 10 to 15 times (short quick strokes) light on ? 
bad bomb (pressure accumulator).
Light not on ? .... Drive car in very safe place speed 65 mph - apply full stop pressure 
to brakes ( I meant emergency stop pressure! ) - ABS actuates several times  ? - good 
bomb ! - light on ? probably bad sensor....
All above assumes booster cylinder has been tested for leaks !
Good luck !
