The Brake that goes click when you stop!

I have a 2000 Subaru Legacy wagon. About a month ago I had a brake job. Since that brake job I get this click sound coming from the passengers front tire. The sound is almost like someone is tightening my lug nut. It also happens more when I am coming to sop when I am going about 10- 20mph. I am hoping that I am not ruining the brakes. I my mechanic is telling me it is nothing and that I should not worry about it. Has anyone had this happen to them?

The mechanic what done the brake job should take the wheel off and see what is wrong with the brake. It’s that simple.

I will have the mechanic look at it soon.

I will have the mechanic look at it on Tuesday
Thanks
