    Noisy Hayes HFX-9

    Now that I've sorted out the pad rubbing problem, my back brake is noisy. It isn't a pad squeal, but more like the rotor is vibrating. I can feel it in the seat. I tried different pads, but the same problem persists.

    Is it a vibration when you are not applying the brakes? If so it's likely a caliper alignment issue. Keep fine tuning the alignment.

    I do this by flipping the bike upside down.

    Losen up the mounting bolts on the caliper.

    Apply the brake to get started with the alignment proces.

    Then slowly turn the wheel and carefully move the caliper until the wheel spins with no rubbing sound. This can take a little while and sometimes you need to move the caliper at the top or bottom bolt only.

    Tighten the bolts in an alternating pattern while hold the caliper until they are both tight. This helps to keep the caliper from moving.

    No, the pads don't rub.
