A left rear 1939-42 Ford brake assembly is illustrated in Figure 25 and shows the mechanism which operates the shoes through the hand brake lever for park ing or emergency purposes. ADJUSTMENTS The major and minor adjustments on Ford hydraulic brakes through 1942 models are made in the same manner as on the Lockheed brake described on page 24. Figure 20. The 1946-48 Ford brakes have brake shoes which are self centering at the anchor pins and therefore there is no anchor pin adjustment to be made on these brakes.
