High Quality Content by WIKIPEDIA articles! The Morris Commercial J4 was a 10 cwt (0.5 ton) forward control van (driver`s cab on top of the engine) launched by the Morris Commercial subsidiary of the British Motor Corporation (BMC) in 1960 and produced with two facelifts until 1974, available with the familiar B series petrol engine in 1622cc form and also, at extra cost, with a 1500 cc diesel unit. Stopping power came from drum brakes all round: there was no servo assistance. Suspension was similar to that on the Austin Cambridge/Morris Oxford of the time: the front independent suspension incorporated coil springs and hydraulic "Lever-type" shock absorbers while the rear springing was achieved by semi-elliptic leaf springs.
