Rear brake shoe lining check (Every 6000 miles or 6 months)
1 Due to the fact that the rear brake drums are combined with the hubs, which makes removal of the drums more complicated than is the case with detachable drums, inspection of the shoe linings can be carried out at the specified intervals by prising out the small inspection plug from the brake backplate and observing the linings through the hole using a mirror (see illustrations).

2 A minimum thickness of friction material must always be observed on the shoes. If it is worn down to this level, renew the shoes.
3 Do not attempt to re-line shoes yourself but always obtain factory re-lined shoes.
4 Renew the shoes in an axle set (four shoes), even if only one is worn to the minimum.
