Had a twig get caught between the rotor and the heat shield once when driving slowly on a road littered with tree limbs/twigs as the result of an ice storm. Backing the car up and turning the steering wheel sharply left and right dislodged the twig.

Another time pulling slowly out of the parking lot at the office and heard a screech and knew what it was. This time not a twig but a small rock. No amount of backing up and turning the steering wheel helped. I had to jack up the car and remove the wheel and pry the heat shield out a bit to let the rock fall free. A tiny pea sized rock shaped very much like a small pyramid. For such a small rock it sure created a big and very annoying sound.

And the other day picking up my 996 Turbo at the dealer and I was driving the car very slowly through the crowded parking lot and I was hearing lots of small rocks, large grit, hit the rotor shields. Fortunately nothing got caught.

 

This has happened to me on my Turbo S about 3 times. Back up fast and then going forward and repeating tends to get the pebble out.

 

 

 

Happened once Put car in reverse and pumped brakes ... pebble dislodged

 

This could be bad news if it happened to your composite brakes. If the pebble grinds a grove into the brake disc it and its neighbor will both have to be replaced, an expensive replacement.

 

yes that’s true - verified via service Mgr..that would be a disaster !

here’s how mine look like when workshop took the wheels off..still stumped how these are bent out of shape, both rears!!
