But the clunking happens only when I apply the brake. For example, I could back out of my driveway, stop, shift into drive, drive for a while (it's maybe 45 seconds to the stop sign) and then when I brake, it clunks (not loudly). Are there are two distinct clunks. I can hear them, and I can feel them, but only really through the brake pedal. It doesn't transmit throughout the chassis.

What are good brake pads? Maybe mine are indeed too small. Can you see that I'm trying to tell myself it's something simple? I might be in that denial phase. So, I don't think it's the flex discs, and I don't think it's the strut rod bushings. This clunking has been there for four months. Doesn't seem to get any worse or any better and I'm not sure if I'm doing harm to the car. I just want to get rid of it because it's embarassing and no noise is good noise right?
