    Ever since I replaced my rear calipers and added teh drilled/slotted rotors I've had this weird hissing/buzzing noise coming from the rear when Im on the brakes. It kind of sounds like a grasshopper in the summer, or even similar to a rattle snake.

    I thought it might be since the slots were "leading" against the forward direction, but I flipped them and they still do it.

    Fluid levels are good and everything is true and balanced. The abs rings arnt rubbing either.

    It's not very loud but I can hear it when doing 35-0 on the brakes when I'm near a guardrail or wall or something with my windows down..

    Anyone know what it could be? It's definately coming from the rear - both sides..

    :dunno:

    Yup I have the same noise in the rear, I have slotted and drilled in the front and they dont do it. Its must just be certian designs make that noise. Sounds like a card in a bycicles spokes to me lol. I wouldnt worry about it.
