Bought my g6 used about 5 months ago, about a month ago my brakes started grinding so I assumed it was just time for a brake job. Replaced all four rotors and brake pads, and the grinding went away for a few days until I started to feel a vibration coming from the passenger wheel. Checked it out, my caliper for that sole wheel was burning hot and the brake pads were smoking. I believe the caliper is sticking which is causing it to warp the rotor. Anyone with a similar issue or solution?
