linings wear. The adjuster mechanism also adds the

safety feature of maintaining adequate pedal reserve

during the service life of the lining.

the adjusting cable (CJ/Scrambler) or actuating lever

(Cherokee, Wagoneer and Truck) lifts the lever into en

cations until the drum-to-lining clearance is reduced to a

point where shoe movement is no longer sufficient to

cause the adjuster mechanism to lift the lever to the

next adjuster screw tooth.
