I recently replaced my front rotors, brake hardware and pads (ceramic), after I replaced everything the front end started making a knocking noise whenever I press on the brakes (both sides). I did some reading and one site said that I could have gotten bad pads so I replaced those again. The noise stopped and after driving for about 100 miles the noise came back. Not sure what to do, everything was torqued to spec. and all clips and shims were put back on. I even bought a new shim set, but could only put one shim per side. Does anyone have any idea as to what the knocking is, it only does it when I push on the brakes.

Sure its the front?

My rear caliper was doing this... basically the slider pins get rusty/gunky over time and services. My caliper was walking in & out crooked, which resulted in uneven pad wear. Think diagonal.

It would click as your describing with light brake applications, or coasting with the brakes barely on. I thought it was warped rotors but as it turned out it was a caliper closing & opening 'crooked'.

It's hard to explain but check out the wear on the pads.
