Braking system / Rear brake shoes - inspection and renewal


Inspection
1 Jack up the rear of the vehicle and support it on axle stands (see УJacking and vehicle supportФ). Chock the front wheels.

2 Working beneath the vehicle, remove the rubber plugs from the front of the backplates and check with a torch that the linings are not worn below the minimum thickness specified.

On completion, refit the plugs.

3 Remove the rear wheels.

6 Check that the handbrake is fully released, then withdraw the brake drum. If difficulty is experienced, the brake shoes must be backed away from the drum first. To do this, insert a screwdriver through one of the bolt holes and push the automatic adjuster wedge upwards against the spring tension. This will release the shoes from the drum.

7 Brush all dust from the brake drum, shoes and backplate whilst taking care not inhale it.

Scrape any scale or rust from the drum. Note that the shoes should be renewed as a set of four.

8 Using a pair of pliers, depress the steady spring cups, turn them through 90∞ and remove the cups, springs and pins (see illustration).

12 Grip the strut in a vice and release the shoe, then remove the wedge and spring. The backplate and stub axle may be removed if necessary, by unscrewing the four bolts after removing the wheel cylinder. Note the location of the handbrake cable bracket. If the wheel cylinder is being left in position, retain the pistons with an elastic band. Check that there are no signs of fluid leakage and, if necessary, repair or renew the wheel cylinder.

Fitting
13 Fit the new brake shoes using a reversal of the removal procedure. Note that the lug on the wedge faces the backplate.

14 Check the brake drum for wear and damage.

15 Before refitting the brake drum, smear the lips of the oil seal with a little grease.

16 Refit the drum onto the stub axle whilst taking care not to damage the oil seal, then lubricate the outer taper roller bearing and fit it onto the stub axle.

17 Fit the thrustwasher and hub nut then tighten the nut, hand tight only.

18 Refit the wheel.

19 With the hub cap, split pin and locking ring removed, tighten the hub nut firmly while turning the wheel in order to settle the bearings.

20 Back off the nut then tighten it until it is just possible to move the thrustwasher laterally with a screwdriver under finger pressure. Do not twist the screwdriver or lever it.

21 Fit the locking ring, together with a new split pin, then tap the hub cap into the drum with a mallet.

22 Check that the brake drum rotates freely then refit the roadwheel(s) and lower the vehicle to the ground. Finally, fully depress the brake pedal several times in order to set the shoes in their correct position.
