Anyone have it?  Chasing a front end rattle forever and it seems it may be the caliper.  Bolts are all torqued to specs.  Brake works great (had to get on it hard today from an idiot!) But it does wiggle just a bit by hand.

I suggest checking your rotor aint bent.  If its warped it will bounce your caliper back and forth.

It shouldn't be too hard to just see if they are. But another indication of looseness or warped parts up front are found if you do a small ride and only use your rear brake.  Once stopped feel your front brakes, If your front brakes are smoking hot they are likely warped a bit and rubbing the pads back and forth.

I just went out to the garage and gave my caliper a shake. If I shove it back and forth on the slide pins, and twist it at the same time I can make it rattle. It's just audible in a quiet garage with the bike stationary and not running.

My front brake is fine, and I've never heard this while riding the bike so I suspect it's normal.
Of course I wear a full face helmet and foam earplugs when I ride, So unless the caliper fell off and was bouncing against the spokes I don't think I'd hear anything anyway.

If you are getting a single clunk over bumps your noise might be something else.
