My wife has a 2002 Grand Am GT V6. EVERYTIME I depress the brake pedal, it sounds as if there is a spring 'binding'. It only does it on the driver's side only. It does'nt do it at all when the car is off... only running. Anyone know what this binding sound might be?

a springy noise can sometimes indicate a rotor and pads that are worn thin the caliper piston over exends and makes a creaking type noise, check your rotor and see how thick the lip around edge is, if its fairly thick your rotor is too thin. They are a quick swap if you have a caliper tool to push the piston back.

Before you go after a brake job try lubing the caliper piston on that side. Just remove the caliper, pry the piston dust boot back with a pocket screwdriver and apply lube in the crevice.

There's a bulletin for a "creak" noise while depressing the brake pedal on GAs. It calls for Kluber lube or something like that.

careful with that dust boot...

you can feel the rotor without actually taking anything off if you have accesibility through your rim.
