tik tik sound while braking

maybe a pebble caught in the disc/pad?

 

Even something caught in the tire Treads could make that sound happen. Then again - warped rotors do it too. If it's not something glaringly obvious, best to have the tech look at it.

or a time bomb...

 

Oops! That's a keyword!!!

 

Does your model have hub caps ?
If you actually hear this and not "feel" it, then it is often caused by a loose rock inside a hubcap......or similar.

As mentioned, it could be a rock in the tire tread too........or a nail or other hazzard stuck into the tire.

 

I would think the foreign object in the tyre would make a note at all speeds.

 

Well of course it does but as speed increases, other noises tend to cover it up.

And one more thought: Sometimes the ticking noise is the hubcap itself flexing because it isn't solidly in place.

 

Your C must be much noisier than my hatchback.

 

It gets easier & easier to hear noises that used to get masked by many other driving sounds. The Continental Tires on obe if our current car has a foam liner attached to the inside because the car is so quiet the tire noise is more noticeable. Ergo they use foam to muffle even the normal sounds of tires traveling down the freeway.

Could be a cracked rotor.

 

If the tik-tik is only there when you're braking, not there when you're just coasting, I don't think it would be pebble in tread.

 

Could be an axle problem?

There is a similar post and thread in the Gen 4 Maintenance forum:

Just realised Asifpop has already found it.

 

So what was it ?

 

Lots of Gen 3 do this too. It seems to be a common sound.

 

Sounds like a bad case of:--

.. we don't know what it is, so it's perfectly normal. Ok?

 

I was thinking CV joint.
