ticking noise from brakes...?

hey guys quick question, how normal is it to have that ticking/crackling noise from the brakes after you drive hard and stop/turn off the car. last couple days after a good hard drive ive noticed those noises when i turned off the enige and stepped outside the car. not sure if its from the brake components but iam pretty sure thats what it is. It makes sense for it to be that, and to some extent normal.. let me know

If its the brakes, then you would be able to smell them, and they smell bad.

But the sound you described, is a typical sound that is made by catalytic converters.

i have the same tick - hasn't been a problem yet. I also have sizzle sounds when I turn off the car after a hard drive with the A/C on. I'm assuming it's condensation dripping onto hot exhaust parts....

The car makes all sorts of interesting noises!

Completely normal. And, it will lessen as you heat cycle them more. Of course, that means you are that much closer to needing brakes, but so what?

Mine do this pretty much every time that I drive the car.. I think it's just the brakes cooling/contracting. Correct me if I'm wrong.

Normal, and if you drive the car hard you will notice the ticking is louder

^^Totally normal!! Did you see this video of Albert Biermann talking about the new M5 brakes... it was on the front page a few days ago. The M5 brakes make the same noises. The noise comes from the different metal expansion rates. Alloy hub vs steel rotor and the oins used to connect the two different metals together.

Totally normal, it is more evident and louder the harder you drive.

When cooling, the contracting disc slides against the floating pins causing the clinking sound.

Especially the OEM brakes. Never really noticed it on my BBK too much but after the switch back for VIR found them to be popping and ticking for quite a bit of time, but seriously, walk the paddock after a session and it sounds like a poor mans orchestra out there

clinking break noise while tracking (OEM breaks)

Hi Everyone,

I am new to the forum and let me first thank you all for such a great source of info. I started tracking my 09 M3 e92 this year here in south Florida (PBIR), so before my first track day I had a ton of questions, and I lost count of how much I read through the forums, just an amazing source of knowledge.

My car is 100% stock, including breaks. I also heard this kind of noise (I guess it is the same) but while tracking the car on Palm Beach (PBIR), not only while parked after each session. I can describe it as if a rock or something hard was stuck in the front tire (no vibration, no fade, no change in break pedal feel, just the noise). After 1 cool down lap it went away, then again after 2 or 3 hard breaking at the end of PBIR back straight (At my beginner level, breaking from 120/130mph to 50mph) the sound would start again. Then, when the session was over and I was parked i could hear the same clinking as described by you.

anyone experienced hearing it while driving (track), and it stops when you cool the breaks down?

Thank you for any inputs!

I love the snap crackle and pop. I can almost watch my exhaust tips retract as it cools down...brakes are boring to watch. Just normal thermal dynamics of metals heat cycling from hot to cold.

sounds like maybe the infamous rock in the dust cover. I had an intermittent popping noise due to a rock in one of my rears that lasted a week. It was eventually eaten or spit out.
