Questions about "click" sound from brake area.

Ive had the problem since I've owned the car, and could never track it down. Everytime my car goes over a dip crack or pothole, I have a clicking sounds that comes from the brake area. The click will stop whenever I apply the brakes. I never noticed that at first, so I replaced all the springs, struts, bushings, end links, wheel bearings, etc. You can imagine how irritating it is whenever you go over a little gap in the road and you get a click...try driving on a crappy highway...Any ideas?
 
I have the same problem...and it took weeks to narrow it down. I would hear it almost as a tapping, or rapid clicking from the front of the car. It sounded like something was loose. I put it on the lift and banged the crap out of everything with a hammer...then put it on the drive-on lift and did the same. I could hear it, I just couldn't find it.

Finally a few weeks ago I had my LH wheel off and accidently hit the caliper with my hand and heard the noise. The bottom caliper bolt was tight, but the caliper itself has play in it. It allows the pad backing to vibrate, or "click" on the spindle. When I apply the brakes the caliper doesn't have this play and the noise goes away.

Long story short, remove your wheels and see if your caliper has play. If it does you should hear the pad hitting the spindle causing the noise.

I am replacing the rubber bushings with metal ones in hopes that it clears the issue up, if not I am going to replace both calipers and see if that solves the problem. If not, it might be in the spindle itself allowing the bolt to have play. I will know more in the next few days.
 
Fett has the right idea. The calipers float in the slide pins and make a little noise sometimes. The brakes actually experience harmonics that cause them to rapidly vibrate and that can cause chatter. When you apply the brakes, it loads the calipers so the noise stops.

It's definately something to check.
Good luck.
 
Ok, I installed my Steeda SS caliper bushings last night. Worked perfectly. I reused the calipers and pads, but I did turn the rotors while I had the car in the air. The install was a pain, because I started the install with the caliper on the car. After realizing that it was damn near impossible (for me) to get the new bushings in straight, I went ahead and removed the calipers from the car. By putting each caliper on a bench in a vice, it went MUCH smoother. Using a block of wood and a hammer, I was able to tap the bushing in, then smack it tight without damaging anything.

Time to install bushing #1, on the vehicle: 20 mins
Time to install remaining 3 bushings with caliper in vice: 2 mins.

After reinstall and bleeding, slapped the calipers with my hands to see if there was still any noises...which there were. So I expected to hear the same sounds while driving, but they were quiet.

I took the car down a bumpy road near work and didn't hear a sound. The click/clacking sound was completly gone. Brakes feel pretty much the same, I didn't do any high speed stops so I can't attest to better braking.

So all in all it was a great investement. For $35 and an hour of my time...the sounds are all gone.
 
I used to get a 'clicking' noise when I drove over bumps in the road. Here is michigan bumps are pretty constant so that noise got to be really, really annoying.

I too took everything apart to find one of the rubber bushings completely missing from my caliper. After I installed the Steeda metal sleeves the noise went away.
 
Noise over things like speed bumps can also be end links. When I hear that very light click at extremes in suspension travel, I generally tighten them up a little bit (I almost need to use some blue threadlock on those - the nut likes to walk).
 
I had a similar problem. I removed the bearings and greased and reinstalled. The right side, the side making noise was a little loose. Tightned properly and the noise was gone. I see you said you replaced the bearings but just wanted to share my fix for a similar problem.
