Brake rattle

I have a 2014 2.0 t r spec and need some input when I am driving and I'm off the brake i hear a rattle coming from my wheels. i did my brakes and noticed the screws for the rotors are gone could that be the cause of the rattle i did the brakes thinking that would stop the rattle but it sounds like it got worse to me.

Remove the rear rotors and see if the threaded part of the screw broke off. Happened to me. Thing was rattling until I removed the rotors.

Lug nuts keep the rotor tight. How are the top spring clips? There should be a bit of tension on the top of the pads.

What pads? Some may require grease on the back of the pads where the pistons hit the pads. Though I have not yet found this necessary. Do the pads have a shim backing plate?

Must not be the brakes then. Maybe a heat shield needs repositioned?

FYI, the screws are there to keep the rotors on during assembly. Once the car leaves the factory, they have no further use.

This .. wont be easy to diagnose over web browser, one needs to see the car to actually assess whats wrong - no crystal ball over here.

That said ... it still may be brakes, i just did turn my brakes to be paraell with the axel within 0.002 mm.

You say you 'did' brakes... rotors AND pads or only pads?
Did you measure the run out of the rotors ?
Is the rotors surface even ?

Best would be to create video with sound of the rattle and then video of your brakes examination

If that is the case then it must be the pads rattling when the pistons are retracted. See if you can replicate it with the wheel off and looking to see if the pads are loose enough to rattle. But if they are I don't know what to do about it.

What was the part number of the pads?

That's what I think it is also cause if you rapid tap the brake pedal you can kinda hear that same rattle.

Maybe do measurements of the pads against OEM pads ?
Like the notches that go into caliper mounting bracket. 1 mm smaller than OEM and you may get a rattle.

I would pull off the caliper and check if you can move the pad longitudinally (front and back). If there is slack there, it may be that.

Also maybe worth bleeding lines with new fluid ?
