Braking system 9•56.3 Depress and turn the cups securingthe brake shoeswheel cylinder and backplate. Take great carenot to inhale the dust, as it may containasbestos.4 If required, remove the hub from the drumas described in Chapter 10.InspectionNote: If a brake drum requires renewal, BOTHrear drums should be renewed at the sametime to ensure even and consistentbraking. New brake shoes should also befitted.5 Clean the inside surfaces of the brake drumand hub, then examine the internal surface ofthe brake drum for signs of scoring or cracks.If any deterioration of the friction surface isevident, renewal of the drum is necessary. Todetach the hub from the drum, refer toChapter 10.Refitting6 Check that the automatic brake adjuster isfully retracted, then refit the drum/hub to theaxle. Tighten the retaining bolts to thespecified torque.7 With the brake drum refitted, refit theroadwheel. Fully depress the brake pedalseveral times, to actuate the rear brakeadjuster and take up the adjustment. Checkthat the rear wheels spin freely when thebrakes are released, then apply thehandbrake, lower the vehicle and tighten thewheel nuts to the specified torque.6.4a Detach the lower pull-off spring6 Rear brake shoes - renewal2Warning: Drum brake shoesMUST be renewed on both rearwheels at the same time -NEVER renew the shoes on onlyone wheel, as uneven braking may result.Also, the dust created by wear of theshoes may contain asbestos, which is ahealth hazard. Never blow it out withcompressed air, and don’t inhale any of it.An approved filtering mask should be wornwhen working on the brakes. DO NOT usepetroleum-based solvents to clean brakeparts - use brake cleaner or methylatedspirit only.1 Remove the rear brake drum with referenceto Section 5.2 Note the fitted positions of the springs andthe adjuster strut.3 Depress the cups holding the brake shoesin position and rotate them through 90° torelease them from the locking pins (seeillustration). Carefully remove the cups andsprings, then withdraw the locking pins fromthe rear of the brake backplate.4 Lift the shoes from their lower pivot andremove the lower pull-off spring (seeillustration). Note that on some models antirattleshims may be fitted between the brakeshoe and the lower pivot (see illustration).
