Question

Quizplus · Accepted Answer

Both technicians are correct. The height-sensing proportioning valve can use a rotating cam mechanism as described by Technician A to adjust its split point based on the vehicle's load and height. Technician B is also correct in stating that levers are used in conjunction with the height-sensing proportioning valve to mechanically link the valve to the vehicle's suspension, allowing it to sense changes in vehicle height and adjust brake pressure accordingly.
