Strange clunking noise after car is idle - BMW 1 Series Coupe Forum / 1 Series Convertible Forum (1M / tii / 135i / 128i / Coupe / Cabrio / Hatchback) (BMW E82 E88 128i 130i 135i)

I've noticed over the last couple months once the car has been idle for a period of time and I start driving it makes this strange clunking noise especially the first time I break. I've searched the forum and it seems as though others have had the same issue but it's not only once or twice it's all the time. I called my SA and he said something about the rotors changing positions or something like that and it's normal? Just wondering of anyone could chime in about this.

I get a big pop sound when I first apply the brakes in the morning. Almost a metallic clank sound (only happens the first time I brake after that it goes away). The brake pedal is sticky when at a light with prolonged braking. After a few miles it goes away.

It's at BMW now for service.

Do you happen to back into your parking spot? The pads have a little float front-back and will shift when changing direction, at least they did on the last car I had with brembos. When you brake for the first time, the pads then shift to the other side of the caliper and can make a light clunk.

Well when I reverse out and brake going forward it clunks pretty loud. audible to people 20-30 feet away. But the rest of the day it won't do it. no matter how long my car sits. BmW kept my car till maybe after xmas.

which sucks cause I just got your package in today lol

b1aze · 12-22-2012, 02:24 PM

Yeah it's just the pads seating toward the rear. I would imagine if you went from going forward to reverse and stopped fast, you would get the same clunk. It's pretty normal with brembos in general.
