With this safety disc brake, all requirements due to regulations can be fulfilled with a constructional effort which is about equal to that for a simple construction. The fulfilment of the most important safety requirement is achieved thereby, that two partial systems, which each operate mechanically completely independent of the other, are provided in the form of two identical brake levers (4) each with a respective separate compression spring (7, 8), which are supported at a common spring abutment centre (2.3) and which is in its turn connected fast with a machine part (1). As further feature for the fulfilment of the safety requirements, both the partial systems display no mutual mechanical interpenetrations and overlappings. The clearing function of the brake takes place electromagnetically by means of a pot magnet (5), which is rigidly fastened at one brake lever (4) and an armature plate (6), which is likewise rigidly fastened at the other brake lever (4). The fastenings of the pot magnet (5) and the armature plate (6) at the brake levers (4) are adjustable in order that the armature plate (6) is always attracted exactly parallelly by the pot magnet (5) and thus no impact noise is generated.
