Drum Brakes

The single anchor dual servo brake assembly is used on all models except "F" Series Super Duty. This assembly consists of a support plate, 2 brake shoes, return springs, automatic adjuster components, and a wheel cylinder.

The automatic adjuster consists of a cable (with hood and anchor fitting), a cable guide, adjusting lever, adjusting screw, pivot nut, socket and spring.

The adjuster uses movement of the secondary shoe during reverse brake application to turn brake adjusting screw and maintain proper lining-to-drum clearance.
