A spring loaded cross steering tube is used giving a toe in of 1/4". BRAKES. Lockheed hydraulically operated four wheel brakes are employed. The system is simple. The brake pedal operates a piston in a master cyl. which is connected up by oil pipes to a cyl. in each brake drum. The brake drum cyls. are fitted with two opposed pistons connected to the brake shoes. The master cyl. is enclosed in an oil reservoir and any loss of oil is automatically made good provided the oil level in the reservoir is correct, it is also claimed that constant volume is retained in the system irrespective of temperature conditions. Brake adjustment is carried out by moving every brake shoe further from its operating piston. This is carried out quite simply from outside the dust covers. STEERING. A cam and lever type of steering gear is used which appears to suffer from excessive slack. 2 1/4 turns of the steering wheel are required to move the road wheels from one lock to the other. The column is supported on the chassis side member and on the instrument board; an outside pendulum lever is used. SUSPENSION. Semi-elliptic road springs are fitted front and rear; the front springs are anchored at their rear end, the swinging shackle being on the dumb iron. Watson XXXX Stabilators are fitted to each wxt axle set at 34 lbs. on the front and 28 lbs. on rear. contd :- | ||
