Rattle/clicking over bumpy surfaces gone when brakes pressed. What is it?

Hey everyone.

I tonight Id mine the tech-savvy brains here with a technical inquiry. For the record, this forum has been a FANTASTIC source of information. Just in the last month I was able to resolve two issues that could have cost hundreds of dollars on tech fees by searching here.

Back to the issue: Im getting a subtle rattle/clicking sound from the front left wheel area when driving over uneven surfaces and bumps on the road. The sound stops immediately once I depress the brake pedal. I had asked a tech friend of mine who suggested that it could be the sway bar linkage. Im a little sceptical because Im not sure how pressing the brakes would make the sound stop, but then again, Im not a technician.

Any ideas what this might be?

The braking would put at least some pressure on the linkage or bushing and may very well take the 'rattle' out of them temporarily. I'd inspect them and give them a very hard shake/pull to see if there's any movement. Doubt it could be the brakes as they aren't drum brakes where there could be a broken spring moving around in there.

Easy way to find out if your friend is right. Unbolt both sway links from the bottom. Swing the bar up and tie or bungee it out of the way. Go for a drive. If the sound goes away, there's your problem. Easy to replace if you can confirm they are the problem.
