To adjust the brake control cable, use eigher the adjusting screw [1] at the
hand brake lever or the adjusting screw [2] at the brake backing plate. Before
commencing to adjust the cable, always release the counternut [3]. Afterwards,
the counternut must be retightened. Regarding the rubber protection piece,
proceed as for the front-wheel brake.
After adjusting the cable, always check if the wheel turns smoothly.
Checking the rear brake linings for wear
The brake linings must be replaced when the distance between the hub brake
lever and the cable support, measured with the brake lever squeezed, is less
than 50 mm (2 in) (see illustration).

If the brake linings are replaced too late, i.e. when the lining is partly or fully
worn away, the metal shoes will rub against the brake drum, thus reducing
the braking effect and destroying the brake drum.
Drum brake maintenance
Drum brake maintenance is limited to occasional blowing out of brake drum
and brake shoes. Brake drum and brake linings can be slightly roughened with
an abrasive tape.
