2. Automatic slack adjusters (ASA). A self adjusting slack adjuster is a ratchet wrench built into a manual slack adjuster. The ratchet drive rotates slightly during either a brake application or during brake release depending upon the design. When brakes are in proper adjustment, the ratchet decouples. As the lining wears, or as the drum expands, the ratchet drive continue to adjust to combat the additional stroke length.There are two design approaches to brake sensing. One method senses clearance or load sensing and adjusts at the early part of the brake application. The second method senses stroke and adjusts at the end of the brake release stroke. ASAs are mandatory on all new air-brake equipped tractors and trailers in the US.3. Antilock Braking Systems. ABS systems are designed to prevent tractor jackknifing or trailer sluing. Electromagnetic sensors, mounted on wheel ends or inside the axles, sense wheel rotational speed. An electronic control unit (ECU) monitors the information from all the sensors and compares the wheel speeds. As the vehicle decelerates, the ECU senses when any wheel is decelerating too rapidly, indicating that the wheel is approaching lockup. When this happens, the ECU sends a signal to solenoid valves that reduce air pressure in the brake chamber. When the wheel deceleration rate changes, air pressure is restored. The sequence occurs in microseconds. End result is smooth stopping of semi-combination vehicles in a straight line. ABS is now mandated on all new tractors and trailers built in the US.
