Car makes clicking noise when driving?

I recently changed my brakes on my SRT Challenger, however, after a couple of days, sometimes when I’m driving slowly, maybe up to 30/40 mph, a clicking noise occurs on the rear passenger side wheel. It progressively gets louder until it stops. And it doesn’t do it every time I’m driving. Sometimes it does it at the beginning of the drive, and sometimes it does it at the end. What could possibly be making the noise? It was the first time I changed brembo brakes, so could it have something to do with that?
