Where should brake grease be applied when installing a caliper pin?

The diagram highlights the caliper pin's contact surfaces (shown in magenta on the pin where it slides between the caliper and spindle/knuckle) as the areas to coat with brake grease.

What should be inspected after installing the caliper pin?

After installation, inspect to insure that the pin tabs are free to contact the spindle flanks on each end of the pin.

What components are involved in the caliper pin installation shown?

The diagram labels the spindle (knuckle), the spindle flank, the brake pad, the caliper, and the caliper pin coated with brake grease.

Where does the caliper pin sit in the assembly?

The pin slides in between the caliper and the spindle (knuckle), with its tabs engaging the spindle flanks at each end.

1. Install the caliper on the spindle, making sure the mounting surfaces are free of dirt and lubricate the caliper grooves (not the spindle/knuckle) with Disc Brake Caliper Slide Grease D7AZ19590A (XG3) or equivalent.
2. Position pin with the pin retention tabs oriented adjacent to the spindle groove (NOT the caliper).
3. Tap the pin on the outboard end with a hammer. Continue tapping the pin inward until the retention tabs on the sides of the pin contact the spindle face. Repeat procedure for the lower pin. CAUTION: During the installation procedure do not allow the tabs of the caliper pin to be tapped too far into the spindle groove. If this happens it will be necessary to tap the other end of the caliper pin until the tabs snap into place. The tabs on each end of the caliper pin MUST be free to catch on the spindle flanks.
4. If removed, install the brake hose to the caliper and bleed the brakes.
5. Install the wheel and tire assembly. Tighten the lugnuts to specification.
6. Lower the vehicle, check the brake fluid level and fill as necessary. Pump brake pedal and check brakes for proper operation.

This document is an illustrated service diagram titled "Caliper Pin Installation," showing how a disc brake caliper retaining pin is installed on a sliding-caliper front brake assembly. The left illustration shows the caliper pin being inserted between the caliper and the spindle (knuckle), with callouts identifying the spindle (knuckle), brake pad, and caliper, and highlighting (in magenta) the surfaces where brake grease should be applied to the pin. The right illustration is a close-up view of the pin seated between the caliper and spindle flank, with a callout labeling the spindle flank and an instruction box stating: "After installation inspect to insure that pin tabs are free to contact spindle flanks on each end of pin." A reader learns where to apply brake grease on the caliper pin, the orientation of the pin relative to the spindle and caliper, and the critical post-installation inspection point — verifying that the pin's retaining tabs are free to contact the spindle flanks at both ends. The diagram contains no part numbers, torque specifications, or explicit year/model applicability, but it was uploaded to a 1983 Ford Bronco gallery alongside other brake-system reference scans.
