Abstract

The abutment of a drum brake is formed from a solid material which deforms under load, wherein measurement devices are provided which detect this deformation. The abutment has two limbs, on which the brake shoes are supported. The changing distance between the two brake shoes under load is determined by detecting the distance between extension rods on the limbs by a measurement device comprising magnets and Hall sensors or AMR sensors.
