Yes, it is a different sound. Recently I took my CTR in for an oil change and the brakes were squeaking something horrible when I pulled in to the service bay. My service writer said he would check that out as well. I told him it was just the brakes and it has done that since day one. Sometimes better sometimes worse. He said the brakes should not squeak. Later he claimed they found several rocks caught in the shield. I said that's fine, but that is not the issue. The service writer was convinced the problem was solved. I drove away with still squeaking brakes. I told my service writer I would be an idiot if I drove the car for two years claiming inherit brake squeal when there were simply some rocks caught I the brake shield.
