Why car vibrate / shake when braking while on gear Drive or Reverse automatic transmission

One unique problem that yet to be solved - the perodua alza car vibrate or shake when braking while on gear Drive or Reverse. It has never happened before it was sent to perodua service center to replace the water pump and serpentine belt (drive belt). There is also feeling like knocking whenever on every turns of the drive belt. Potential cause need to investigate 1. Water pump - loose or pulley misalignment 2. Tensioner Pulley - loose or faulty bearing 3. Spark plug - one of the spark plug not doing its job at optimum conditions. 4. Weak fuel pressure 5. Clogged fuel filter and fuel injectors
