Abstract

The invention is related to a brake shoe with a chamfered edge lining, the chamfered edge achieving desired surface configuration of the lining after only a few braking actions while increasing the service life of the lining. The chamfer has a profile shape which features a hyperbolic contour, steeply angled at the top adjacent the outer face and very shallowly angled at the bottom adjacent the backing plate so that the increment of wear of each braking operation decreases in a strongly degressive way.
