ABS failed, brakes rattled, great perplexity

Hello everyone, I’m new here. We have the following problem: Opel Omega B, year 1998, 2,0 16 V, 136 HP, engine: X20XEV. We bought the car in December, with snow and ice. It was now, on Christmas Eve, no, sorry, it was a little joke, so Christmas Eve I had to drive my husband to Santa Claus appearance, drove into a snowy, icy side road and drove me promptly. Try to get “griff” again by steering, nothing. Until someone with a bit Since then, the following has been done on the car: 1. Brakes in front (dishes and blocks) renewed – no change 2. Cross handlebars in front again (the old jacks were gone anyway) – no change 3. Errors read out – no error, even the MKL or the ABS lamp do not shine 4. Brake fluid renewed – no change 5. Brake discs in front and back checked due to possible damage – all right 6. ABS-St your device replaced, ABS sensors cleaned – no change 7. ABS rings checked – i.e., we are at the end… no one knows what that can still be… Can it be that I may have broken something on the wheel hub or the axle with my steering or what do I know what else there is??? I can only describe the rattling in this way: no matter what speed (at higher you notice it of course more) we brake, the car rattles or stutters at the brake It would be great if anyone here still had ideas… Thank you so much and many greetings from Bremerhaven.
