TO meet the new Regulations in respect of secondary braking, and to conform to the recently agreed standards by the S.M.M.T., Scammell Lorries Ltd. has designed a braking system for artic vehicles using the three-line system and having triple-diaphragm chambers at the front axle of the tractive unit and at the semi-trailer axle or axles.
The service brake operates in the usual way with a foot valve operating all axles of the outfit and a two-line system to the semi-trailer, whilst the emergency brake is hand controlled and operates the tractive unit front axle and, through a third-line, the semi-trailer axle or axles. A separate air-assisted mechanical handbrake operates the driving axle brakes.
