Hi, I have a 97 Maxima, that has been making a noise that you and I have discussed before, well now, I have unusual wear on my right front rotor, it looks like I had a pad wear too far and gouge the disk, but I didn't, it is also the side, under acceleration, that make a squeal, I found that the right side has a bearing, that the left side does not have? could this bearing be bad? It looks as if there is some play under acceleration that is causing the caliper to come into contact with the rotor?!?! Any advise would be greatly appreciated. PS the local dealer had this car for a WEEK looking for this noise, and could not find the cause. Thanks

I'm not sure of this bearing you speak of, maybe you could be a bit more specific as to its location.

you may want to disassemble the right front brake caliper and inspect the pins that slide in and out of the caliper mount.

there are some rubber bushings on the caliper pin/slides, if those are rotted away it can cause the floating caliper assembly to move more than it should

Per NissTech's reply, when I disassembled my calipers I found that some rust had snuck onto the metal mounting pins. They didn't slide very well, causing the caliper/pad to stay in contact with the rotor. I cleaned them off, and re-greased the pins. I haven't had any problems since then.
