I'm just asking before i start jacking up the car to see whats going on. For some reason, when i'm in neutral and i fall backwards a bit and brake, it makes a single click sound. It sounds like it's coming from the front driver side brakes. I have recently put brembos on so i def has to do with that. Any suggestions?

 

Maybe it's you pads shifting?

Or maybe you are hearing what I heard in the following thread, which is a normal noise.
