I had to replace the caliper because it was sticking. I replaced the caliper, brake pads and rotor. However, I'm still getting a gritty grinding noise when braking right before stopping in the front right passenger side (same side as I just replaced brakes, rotors, and caliper). Any ideas? I've read thru everything and saw something about it could be the ESP? I'll try to get a recording of it but you can feel it in the footwell of the front passenger side as well.
