I had loud expensive sounding metalic tapping noise noise under the bonnet that I initially put down to imminent engine demise. Upon closer examination it was a faulty non return valve that sits on top of the servo and connects with the hose linked to the manifold. I had forgotten that I had just replaced this valve with a new one while the car was off the road for a couple of weeks. The symptoms on the pedal were a slight rythmic pulsing with the engine running and the pedal pressed down. Changed the valve and cured problem. As Mark says servos when faulty can chuck up some strange symptoms. I don't think you will ever be thrown through the windscreen by the power of even good JH brakes!
