Default What'* that clicking sound?

I've always had a noise in my car, and it'* very consistent so I though maybe it was normal. I'm just curious what it is, and want to make sure it'* not something faulty. It'* a clicking noise and it seems to be maybe from the front end, but I'm not sure. It happens when the car has been sitting for quite a while like in the morning and when I leave work. I've observed that it happens when I come to my third stop (seems odd), and I'm at a complete stop it will make like three clicks. Then I don't I don't hear it again.

Would it be something like the brakes self adjusting?

You have 4 calipers. No adjusters.

It'* probably your 4-phase variable turbothrusters re-synchronizing themselves with the kinetic-dingoactuator. You need to get a fulcrum analyzer on that thing ASAP to make sure it happens precisely 35 milliseconds after your third stop.



Gonna have to narrow it down, but it ain't brake adjusters.

I know there are four calipers, but I've never dealt with disk brakes so I'm not educated in how they work exactly.

It'* funny how it does it the third time I stop though. It'* a quiet sound, so unless I'm listening for it I don't always hear it. I'll have to refresh my memory today on how exactly it sounds, but it seems like it has a plastic sound to it, and it'* more of a tapping probably rather than a clicking.

Your explanations have been esoterically inane this week Mr. Wren..... Is this the same as taking the playing cards off the spokes. Turn each wheel out and see if the is anything inbetween the backing plate and the rotor etc. first Grimm .

I'll have to check, but I don't think it'* anything like that. It doesn't make the sound until the car is stopped. It'* not like a random noise, it sounds like it'* something mechanical. I know what the self leveling sound is, so it'* not that, but could it be related?

I believe I have heard this sound, but in my GF'* 04 GA. it does it three times rapidly and then nothing. I dont know what it could be either. I thought it might have to do with the fuel system on her car or a fuel valve cycling somewhere I dunno.......

Is it more obvious on cold days? The vapor recovery purge solenoid purges the tank soon after startup. The solenoid clicks, and can be heard for some reason better when it'* cold.

I don't think it'* any different in the cold. One other thing, is that when it does it I'm more than a mile from the house. I back out of the drive, go to the end of the street two houses down and stop, take a left and stop at a corner a block away, and then go close to a mile to a light and stop, tap tap tap. So I guess technically it'* the fourth stop if you count backing out of the driveway.

Is the purge selenoid under the hood? The way it sounds, I thought maybe it was something mounted on the firewall. It'* sort of similar to the tapping I hear from the regulator on my convertible, which is mounted on the firewall.

Yep, both my car, and my friend'* 00 SSEis do the same thing. I was reading about the ABS system a while back, and that after some time the PCM runs a test on the system. It wasn't very descriptive, but that'* what I've chalked it up to.

Hey yeah, I know what you're talking about.... I've heard the same thing on mine. Mine'* not very consistent. It only happens once in a while, and when I've been at a stop for a while (like at a long red light)... I never thought of it as a problem, I just figured it was something with the brakes...
