I have a 05 C6 that is making a clicking sould when I am turning or stopping. It does not do it everytime. I have had the suspension tightend and it is not as bad. I heard that it could be a clip on brakes. Please help on possible fixes. thanks

Other than the obvious with pads and rotor replacement is there any other maintenance as a good rule of thumb that should be done to the brake systems in these cars? Thanks for the input.
