ISSUE: A "rattling" noise may be heard coming from the front disc brake calipers. The caliper pins may eventually take a set under certain load conditions allowing the disc brake caliper to "rattle". The "rattling" noise is more likely to develop on units that are driven off-road or operated on rough roads.

ACTION: To correct this, install new design caliper pins. A new caliper pin removal tool can be made to aid in removal of the pins. Refer to the caliper pin application chart on this page for the correct service part number.

The caliper pin removal tool is recommended for use on all the above listed vehicles, including 1988 Super Duty. This caliper pin tool can be made from a 1/2 inch diameter rod 7 inches long. Simply grind or cut a "V" notch in one end. The "V" notch is used to compress the pin retention tabs while the tool is also used to drive the pin out of the caliper slide groove. This tool replaces a pair of pliers and screwdriver as outlined in the Shop Manual service procedure.
