Ok so last night im driving with the windows down and I start to hear a clicking noise when I brake. Here's the thing it only clicks when im moving foward and start to brake. When I go in reverse and brake its normal.

The noise is coming from the back driver side wheel/brakes. I took the back wheel off and looked at everything and it looks ok.

Now imparanoid bc I feel that the noise (clicking) is something bad and im just messing something up by driving it.

Any advise would help....
