    A common BBDB call we get is about a caliper with the outboard pressure foot dislodged. If the outboard adjustment knob is turned too far clockwise without the rotor in the caliper (wheel off or caliper removed), the outboard pressure foot can be pushed out of the drive cam and float free in the caliper body. The brake is not broken and it doesn’t need to be disassembled to replace the pressure foot.

    To replace the pressure foot, turn the outboard adjuster knob counter clockwise until it stops. If the knob doesn’t stop, then the footscrew (you can see the end of the footscrew in the center of the knob) has become disengaged from the knob, and possibly from the threads inside the drive cam. In this case, remove the knob, then use some small needlenosed pliers or a Schrader-valve tool to turn the foot screw all the way back out until it stops. Once this is accomplished the pressure foot can be replaced. Relocate the pressure foot into the bore, then give it a firm push in the center. It will “click” back into place.

    If you removed the outer knob, replace it, and you’re done!
    nice link. cheers!
