Update guys. It turned out to be the wear sensor on the inside pad. It was BARELY starting to rub against it as the smooth part of the sensor was very minimal and barely noticeable. So that took care of the noise. Now on to the huge headache and the big PITA...it looks like my ebrake cables have gone to rust hell and back. I had a hard time disconnecting the cable from the driver side caliper but finally got it after like a damn hour or so. It was so hard to squeeze that damn spring clip thing together to release the cable. I had to have my friend help me by him pushing that together while I tried to free the cable. The even bigger PITA was the passenger side caliper because somehow, that spring clip thing was already compressed together and would not release and would not allow me to release the cable from the caliper. So I ended up having to disconnect it from the middle of the car where it ties in with the cable from the pedal of the car. Not sure if that makes sense or not. I really just wanted to cut the damn cable and throw the damn thing out in the street as hard as I could. I was planning on spending an hour or 1.5 hours on that job and ended up spending almost 5 on it. I was so damn frustrated and it was hot and I was under no kind of shade. So yea. But basically I ended up disengaging the ebrake system so that the calipers could clear the new pads. Turned out my passenger side caliper ebrake was not releasing all the way and put some drag on the brake for who knows how long. Pads were unevenly worn. Also, what brand brake hardware have yall used? I noticed that when I put the new pads on the driver side, the rotor would not move all that freely with the hardware with the caliper on. If I removed the caliper, the rotor would move freely. Would that be a caliper issue or hardware? I just left it like that cuz I was already frustrated and I just wanted to be done with it already.
