RAV4 Brake Crack?

[Thel]

So, preface to this post, I'm a very paranoid person. But I also am engineering/mechanically skilled to trade. 

Recently got new brakes, about 3 weeks ago, all went well and no issues. Now in the last few days brakes have been squeaking frequently, and they groan badly if I brake at the bottom of a steel incline. 

I had a look at the driver side, which is where the noise mainly comes from, and saw what might be a crack? You'll see it on the pics. Now it kind of looks like a crack, but also looks like it might be a nothing. 

Am I being paranoid or is this something that needs looked at?

Honestly they look like nasty cheap rubbish or they have been hammered in, have the anti-squeal shims been re-fitted and have they been coated with a bit of copper grease or similar product. The pads sound like they are moving in the calliper, if you did not fit them take it back. Have a look at the picture you should have something similar fitted sometimes they corrode and are not replaced the pads will then float about.

Yeah the whole lot got renewed as the brake caliper was stuck on. That's all new 😕

Looking at your picture if that's your breaking system you do not have any of the above you should have shims/plates between the piston and pad, you look like you have a 2007 plated RAV4 these have shims/plates fitted I can't see them in your picture without them they won't seat correctly and squirm about causing noise etc.
