    Q:
    What should you do if there is pulsating during brake application for the 2009 Chevrolet Cobalt due to a Brake Disc issue? Posted by Afzal J.
    A:
    If there is pulsating during brake application, suspect disc runout. To check runout, secure the disc to the hub with lug nuts and place a dial indicator about 1/2 inch from the outer edge of the disc. The reading should not exceed the specified runout limit. If it does, the disc needs refinishing. You can Select Your Vehicle to see complete installation and repair tips.
