| -4- upon going abroad is to tightened up ones shock-absorbers in order to travel with the same degree of comfort as one does in this country. The shock absorbers as at present fitted do not appear to actually lessen the travel of the springs to any extent which is necessary for high speed touring on bad roads. BRAKES: In course of conversations with Mr. Northey and others of your Company, the Writer submitted the opinion that the brake area was less than that of the Hispano-Suiza, and would consequently not last as long as this car if the brakes were to be used consistently and severely. The writer was told, however, that the actual brake area was greater. With this he does not, with respect, agree. Anyway the Rolls-Royce brake drums are of considerably smaller diameter and are also narrower than those fitted to the Hispano. If the same material is used as a braking surface on both cars, and it is used under equal conditions, it is obvious that owing to the smaller diameter the wear will be more rapid on the Rolls-Royce. Anyway, it is suggested that an investigation is made of the condition of the brakes when the car is returned to you. These have not been submitted to any severe strain, but they have had to be adjusted once already and the need for further adjustment is now again becoming apparent. I submit that the need for relining will occur with these brakes about every 8,000 miles if the car is driven in the way in which it has been driven. | ||
