| -3- SUSPENSION. Independent at front, with helical springs and built-in hydraulic dampers, (providing a large wheel movement with an exceptionally comfortable ride both in front and rear seats, with complete stability and ease of control at the highest speeds), the rear suspension employs long semi-elliptic springs with patented hydraulic dampers controlled both by a governor actuated by the speed of the car and an over-riding control lever mounted above the steering wheel. STEERING. Is of the cam and roller type, extremely light but providing exceptional directional stability and safe cornering at high speeds, with a complete absence of road reaction. FRAME. Deep box section side members, the front cross member and central 'X' cross members are also of box section, (thus providing a frame of exceptional rigidity both in bending and torsion with a minimum of weight. BRAKES. Internal expanding on all four wheels, pedal operated assisted by a mechanical servo which is equally effective in both directions, the hand brake operating on the rear wheels only. The brake drums are of cast iron, with deep cooling ribs, which greatly add to the rigidity of the drum. CHASSIS LUBRICATION. Centralised system from a pedal operated pump mounted on the dash, and automatically providing a controlled supply of oil to every point on the chassis including the steering connections, suspension system, clutch thrust race etc. | ||
