all bearings do not need to be changed. only the one which has issue if there is any in the first place.
the test is simple: put the car on jack (wheels up and free). put the car in neutral. put your hand on the shock bar above wheel. turn the wheel by hand. if there is grinding feeling on your other hand that is on shock bar the bearing is bust. repeat this for all 4 wheels. only change the ones which have issue.
regarding brake pads i chose bendix over nisin. they are the best quality and are available for half the price of orignals and they have worked best.
you can talk to Mr Rashid in FSD (03008582519) for getting bendix brake disks of your car. Can give my reference.
