2007 Mazda 3 4 cyl Front Wheel Drive Automatic 33,000 miles
I just replaced the brake pads and disks, the disks were stuck (rusted), I attempted to hammer the back side while spraying some WD40 to loosen them. I finally got them out after 3 hours of hammering. The problem now is there's a rubbing sound comming from one of the brakes. I removed the wheel to investigate the problem and found that one of the disk (on the back side) is getting grooved by the new pad I just installed? Everthing seems be installed correctly, could the hammering have caused some gamage elsewhere?
