Hey Pedro,
I don't think it's the brake caliper for these three reasons:

-Engine needs to be at normal operating temperatures to make clunking noise.
-Noise only happens when car is in gear, accelerating or decelerating within gear. When clutch is engage, noise stops.
-Noise frequency matches the speed of the car, but like mentioned above, goes away at freeway speeds.

I cleaned the caliper by taking the wheel off, then the actual caliper, and cleaning it with brake cleaner. I’ve thought of rebuilding the brake caliper, but I’m stomped as to why this sound happens with the above situations. Specifically why the noise stops if I engage the clutch.

Thanks,
Cesar
