So nothing ever has been wrong mechanically with my 04 rover. Today, I was running some routine errands and when I came to reverse out of my parking spot, I heard this weird bumping and grinding noise. I also felt it through my brake pedal (my parking brake was not on). I thought something was terribly wrong so I immediately put it in forward. I heard nothing. I sped up and slammed on brakes and everything worked perfectly, no noises or vibrations. I then put it in reverse again and felt something again, just not as bad this time. I decided there was nothing I could do but drive home, and along the way I couldn't hear of feel anything more. I am getting no error codes pertaining to "check brakes" or transmission. I have also had the differential call back applied about a year ago. I feel like it could be that my brake pads are completely gone, but I am not getting any error codes. I hope something is not terribly wrong. Anyone had a similar experience?
