One of the common signs of a faulty master cylinder is a slowly sinking pedal when you apply brake pressure. Another common symptom of a failing cylinder is a spongy feeling brake pedal. Unfortunately, sometimes there is no visible sign of a failing master cylinder, even though internal valves are deteriorating. Order a G6 master cylinder replacement from AutoZone and restore the brake performance on your Pontiac.
