Indentified Clunking Noise!

[omron]

Hi !
Last night I notice somekind of clunking noise coming from the passenger side rear end. Everytime I went on some bumping road I could hear this clunking noise. So I decide to investigate in the next morning.

In the morning I decice to jack up my car, while doing that I hit the wheel to check if everything was ok, until I hear that clunking noise. I did remenber doing by brake job a few month ago (only pads). I notice that the aftermarket pads were moving a bit on the galiper about 0.75 to 1 mm . On the top of the rear galiper theres is a space where you slip the pads in, a kind of cavite on the galiper because the pads were aftermarket pads the heads of the pads were too small it was slipping back and front banging on the galiper. So I decide to put a cime or a spacer. I did a test drive and the noise went away like magic

I though that It was a a STRUT BEARINGS issue but it wasnt that! Ihop it can help someone out!
