Back in November I changed my 997 Targa 4s for a 991.2 Carrera S. I would like to know are any other 991.2 owners experiencing squealing brakes when they heat up. It is not happening under hard braking but coming to a junction or moving in traffic. I have been back to OPC & they have checked & greased all relevant parts but with no change, they also said that the new brake pads that are being fitted to 991.2 are made of a harder compound than previous pads to enable superior stopping power !! Whenever I had the chance I would have enjoyed a good run in 997 Targa 4s & never experienced any problems with squealing brakes.
