    Rookie question

    Picked up an '08 Shift R5 that came with Avid BB7s. I had ordered a Shimano XT 775 for a Diamondback that was stolen a couple days ago (thankfully hadnt installed it) and installed them on the new bike. Had to use the Avid rotor because the Shimano was a center lock. Compared to the BB7 caliper/rotor, the Shimano caliper/Avid rotor is very noisy. Brake performance seems good (considerably better than the BB7) but what can I do to alleviate the noise?

    Just to clarify, I'm not getting any squeal just an "abrasive" sound. The fronts dont make the noise, perhaps it's just the pad material of the Shimanos?

    i'm sure the sound will subside as the rotors wear in

    Are the pads making full contact with the rotor (all of the pad material should be touching the rotor surface)?
    I can barely get my mouth around it.

    I'll pull the pads and check but I think I have them adjusted quiet well.

    Maybe the BB7s were "organic" and the Shimano's have metallic? Metallic/semi-metallic pads are considerably louder than organic ones.
