ABSTRACT:
A hand brake for a motor vehicle includes a hand lever pivotably supported on a support bracket fixed to the vehicle body, and an adjusting disc likewise supported on the support bracket and connecting the hand lever with a pull member leading to a wheel brake shoe. A detent pawl supported on the hand lever cooperates with a toothed segment formed integrally with the support bracket and is released with an actuation rod longitudinally displaceable in the hand lever. The hand lever is connectable with the adjusting disc by a coupling pawl supported on the hand lever and slidably engaging a guide pin secured to a side surface of the support bracket. The adjusting disc is springbiased in the rotational direction so that it provides for progressive pull member displacement/force ratio.
