| BRAKES -- There is no compensating device in the ordinary manner, fitted to the brake operating shafts but to compensate for the difference in torsional spring between the levers on the right and left sides owing to the difference in distance of these from the primary lever, we attach the primary lever to an outer tube which extends to the centre of the chassis and is there fastened to the inner shaft or tube to which the side or secondary levers are attached and having the end where primary lever is attached free, thus equalizing the length of shaft in torsion. There are many other special features on our chassis of which if you are interested we will forward particulars. | ||
