I have a 2004 Malibu (Classic) that is squeaking on the left side when braking. I took it in as a warranty item earlier this year, but the dealership put new pads and rotors on and slapped me in the face with a $200 bill (after I told them not to fix it).
I have a few things to investigate the next time I can wrangle the car from my wife. These were suggestions posted on another Malibu website. The caliper hardware is one idea, that being the piston that is making the creaking sound when it moves for whatever reason, and another is making sure the hardware is bolted down as tight as it is supposed to be. I was planning on just buying the calipers, but after finding out it will be about $140 for the pair, I am going to try to exhaust other options first.
Seeing how this car was an Enterprise car in it's former life, I'm not surprised it is having brake problems. Sometimes when you let brake pads wear too low, the pistons in the calipers will either seize up or become damaged from traveling too far out of the caliper and allowing dirt or whatever to get in its space.
Once I have a chance to look and hopefully fix the problem, I will come back and post here.
