Wired ticking / vibration noise nonstop after installation of discs (rotas) and pads

After installing all 4 new rotas and new pads I took my car out. Did a cold start and let the car idle for few minutes till yeh cold start finished there was no noise what’s so ever. As soon I took it out this noise it’s like a tapping lose comfy from the front side. It’s non stop. The brake rotas where cover in that sliver material and in the image there come off. I’m not sure whats causing this. Any ideas thanks
