The standard-fitted Telligent® brake system comprises the regulated dual-circuit brake system, internally ventilated disc brakes all round, ABS, ASR and auxiliary brakes such as an engine brake or retarder. The system relays each brake signal at practically the speed of light – much faster than any mechanical system could. In addition, brake metering is as precise and sensitive as on passenger cars. The brake force is distributed as optimally as possible between tractor unit and trailer or semitrailer, depending on vehicle load.
