Noise After Rear Brake Service

[RoverBoy]

2005 LR3 SE V8 - Replaced rear rotors, pads and sensors. Everthing went fine. During test drive I am hearing a faint scraping noise. It's intrmittent and does not happen while braking and brakes are working properly. Checked both rear wheels for debris and saw nothing. Cleaned all parts carefully before re-assembly. Any thoughts on what it could be or if I missed something?

Did you replace any of the hardware? I.E (not sure on the LR3) springs clips or related pins? Did you grease any of the slide points? Did the breaks come with the anti squeal backing and did you use it or any such thing?
