Sounds like brake pads are somewhat smaller and they are hitting the caliper as they move. Try repeating one movement in one direction multiple times. If it goes away after the 2nd time then changes are I am correct. Because once the brake pad moves to the other end it cannot move further anymore therefor any new braking won't make that noise again (or very little because there will be just a tiny gap). Once you reverse your direction then the 1st brake will slap those pads to the other side and make that noise. Take off the wheels and push back the brake piston a bit using a flat screw driver (carefull not to damage the rubber boot) and then wiggle the caliper paralel to the wheel axles (meaning back and front towards your position if you will be facing the wheel). Once you have the caliper somewhat free to move try to wiggle your brake pads and see if and how much room they have to float around in there. Some brands have little space while others are more generous and it can then produce this exact clicking sound that may seem like something bad but it is just that. To remove it you can use some thick brake caliper paste on the backside of the plates and both ends that "lead" inside their tracks or buy a set of new brake pads that will fit better. Some brands have a metal spring you can mount on the middle/top side of the pads that keep a small ammount of pressure to the pads to keep them somewhat in place but I would not use this as a solution. They may fall off and then you are back in your problem again. So if it is the pads it is not a problem but just annoying. Try and see :) If not then my 2nd guess would be the joint shaft and something around that area. 3rd and last guess - something is not torqued down to specs and is somewhat loose now. Ball joints like to sound like that as well when they are worn or not properly tightened. Or even a wheel with loose bolts :D had this once on a car with refurbished wheels. Guaranteed quality. Turned out they were from a totalled car and the wheel bolt holes slightly twisted from the force of the crash allowing the bolts to loosen themselves every 200km of drive. Just a bit but enough for the cone not to sit flush anymore and the inner walls were somewhat hitting the cone from the side. If I'd keep on driving I'd be hitting the cones more, then the threads and then probably lose some bolts along the way. Took the wheels back to the seller and got my money back. Not sure if anything helps but that is the best I could throw at you right now.
