All these problems with squeaks while braking, my CC does the opposite. It squeaks when i don't brake and not when I do!
Caliper I thought, it must be rubbing on the disc... so I took it to Peugeot....could not find a problem...of I drove...still sqeaks....back to peugeot....5 TIMES IN ALL until I kicked up a stink with Peugeot UK and they said they will shave a bit of the pad. This seemed to cure it until about a month later and it is going back in again!
Anyone else had the same thing happen as I need some more ammunition before my next visit to peugeot.
Also got a very creaky roof on passenger side, esp when I go over rough roads and the ususal poorly fitting windows....
Apart from that .... God I love my CC.... bring on the Summer again!
