---

The rear wheel shoe brakes are adjusted automatically. The pressure bar changes its length with the help of the adjustment unit and maintains the structurally specified gap between the brake drum and the brake shoe.

For automatic adjustment, a wedge with an extension spring is located between the primary shoe and the pressure bar, which lengthens the pressure bar. After pressing the brake pedal once, the gap value is set equal to the specified value. If the shoe movement due to wear becomes greater than the specified gap, the extension spring pulls the wedge down. As a result, the working length of the pressure bar increases, and the brake shoes are automatically adjusted.
