is it diesel? if so then your brake vac pump may be faulty. you could try disconnecting pipe at servo and with engine running feel at end of pipe for a suction/vacuum if none can be felt then either pipe or pump drive or pump itself will be at fault

put your foot on brake pedal & start engine if your pedal start's to travel toward's the floor the servo is o.k,it could possibly be the master cylinder on it's way

chech servo pipe is not split or disconnected if ok sounds like your servo is at fault
