Abstract
Abstract An installation for preventing the locking of brakes in vehicles, preferably in motor vehicles in which sensing members are provided at the wheels that supply to a common comparator an output signal corresponding to the wheel rotational speed; each sensing member is thereby arranged on the inside of the corresponding wheel mounting, preferably between the inner wheel bearing and outer wheel bearing.
