Guys, I've changed the discs and the pads long ago, and it started to wiggle a lot after 2 months. Then I went back to my old disk because I thought it might be the disc, and it stopped. 2 months later, it started wiggling again.

What could it be ? Are my pads bending my discs ? Or what is happening. But it's something because in some situation it doesn't wiggle
