Ford Bronco Brake Booster Pushrod Adjustment Diagram - Gauge Block Specs

This document is a labeled technical diagram titled "Brake Booster Pushrod Adjustment," uploaded to a 1992 Ford Bronco gallery. It illustrates the use of a gauge block placed against the face of the brake vacuum booster to check and set the length of the booster pushrod via its adjustment screw. The diagram shows a cross-section of the booster mounting studs, the pushrod extending through the gauge block cutout, and the adjustment screw tip contacting the gauge. Key dimensions are called out: the gauge block overall height of 74.61 mm (2-15/16 inch), a 19.05 mm (3/4 inch) dimension for the center cutout, and the critical pushrod protrusion specification of 24.89-25.27 mm (0.980-0.995 inch), with the 0.995 inch depth shown as the gauge step. The figure carries the Ford illustration reference H1330-J. A reader can learn the correct gauge block dimensions to fabricate or verify one, and the proper pushrod length range so that the adjustment screw is set correctly, avoiding brake drag (pushrod too long) or excessive pedal travel (pushrod too short). The document itself gives no year, model, or engine applicability, so it does not contradict the claimed 1992 Ford Bronco.
