Again steering wheel flapping while braking.

Hey guys. ALso now to my problem. My 406er has already eaten 3 sets of brake discs this year + 2 sets of pads. So the first were brake discs from the previous owner on it & found it about 4 months after the purchase that it flutters while braking. Okay, brake discs + pads in front. No great quality. i.what accessories from Peugeot dealer After about 2000km the whole shit started again, & It squeak at the same time as if something had a “eight”. Chlechter quality. According to statement by Peugeot, my wheel bearing v.l had a game. Okay, the wheel bearing & hub front left replaced. Then new brake discs built by FEBI + Org. brake pads Peugeot, of course support surfaces wonderfully clean made. All 4 tires completely redesigned. At the same time almost complete ha renewed. Both carrier plates, brake disc + pads, brake calipers, hand brake + Bowden trains etc etc…. And now it starts again, about 4000km later & 2 months… Al so nothing else can be like that again or?, because if Radnabe or something else had a defective, the fluttering would be already available from the new BRemsen up to now or do I see something wrong? Data about the car: Peugeot 406 year 1998 3003/770 2.0L petroler. Brake system Lucas. Steel rims (fehtl eventl ventilation?) 155000km I need help. The brake eats me & my portemoney!!! Greeting
