Single 'click' when braking Options

[RoadRage]

Since today, every time I brake firmly there is a single 'click' that comes from the drivers side wheels..

It doesn't click if I do a slow or gentle brake, only when it's a bit more firm.. I've tried in both forward and reverse and it does it..

Would anyone know what It could be?

Brake pads moving or ball joint?

Thanks

I have a similar problem at both sides and afer I checked it a lot I found that the inner break pads move inside the caliper.
I don't know if there is something missing from my brakes but it does it on both sides. I 've been thinking to replace the springs
insight the caliper but do you thing this will be enough?
And in case someone alse have similar problem if you ffell under the rear end and try to move the pads with your hand, you will
replicate this sound without much effort.
