A brake system for a passenger transportation system includes a brake lining and a brake surface, wherein a gap exists between the brake lining and the brake surface when the brake system is in an open position. The brake system also includes an optical monitoring system and a processor. The optical monitoring system has a light source arranged to emit light towards at least one of the gap and the brake lining, and a light detector arranged in a light path of the light emitted by the light source. The light detector generates an electrical signal as a function of impinging light. The processor is coupled to the optical monitoring system to receive the electrical signal and to generate a predetermined indication if the signal indicates a value that is equal to or greater than a predetermined threshold value.
