(G). BRAKES. Both internal expanding direct on rear wheel hubs, enclosed and protected from road dirt and oil and compensated by bevel gear equalisers of RR. pattern; the brake shoes are of aluminium, and internal and external adjustment is provided close to the point of wear. The brakes are remarkable for their smooth and effective action, the special RR. cams which have great efficiency and equality are used to expand the shoes; it is very noticeable how the rear axle steadily keeps on to the road when the brakes are applied, resulting in a straight, powerful, and smooth pull up of the chassis. (H). BACK AXLE. Is of very light construction having aluminium central box, steel tubes with large flanges and a substantial tie rod; it is extremely compact for the diameter of the bevel gear. The road wheels are entirely mounted on extensions of the tubes (termed "full floating") therefore no part of the rear axle is subject to reverse stresses due to the weight carried, the internal driving shafts being subject to torsional stresses only. The bevel gears are spirally cut and the pinion is fitted with a third (nose) bearing so that it's alignment is maintained. The silence and durability of the nickel steel case hardened bevels is extremely great owing to the effective support of both members of the bevel transmission. (I). FRONT AXLE. The front axle is a high tensile alloy steel forging of I section of light and accurate proportions, also the stub axles which are of large diameter carefully radiused and bored for strength and lightness. The steering pivots are arranged to give "centre point steering" so as to reduce to a minimum the (6) | ||
