| -2- (4) Rear Brakes. Evidently the Slade lining is exceptionally good but we have to remember that often when a lining gives excellent service in severe use it will squeak after storage. Even the soft J.{Mr Johnson W.M.} M.{Mr Moon / Mr Moore} lining we are using does this. Note: As it happens on almost these same days a friend of ours made almost the same identical trip on a new Packard and noted that:- (1) In spite of frequent overhauling they made 75% of their 6,500 mile trip virtually without brakes. The "self-wrapping" Bendix brakes would accumulate sand and act like a "sprag", so that the only way they could be applied safely was by stepping on the accelerator at the same time that the brakes were applied. Actually they used 1st. speed instead of brakes. (2) The Packard hydraulic shock absorbers "quit" a t air temperatures above 100°F.{Mr Friese}, so that they could not drive in comfort at any speed. (3) In hot weather on the desert they had to fill up with water about every 20 miles. This apparently is common on all makes of cars, and the R.{Sir Henry Royce} R.{Sir Henry Royce} appears definitely better than most even without bonnet shutters. He noted that a lot of the time they were running in sand or gravel up to the cross-members of the frame. Under such conditions and air - temperatures of 120° plus, one would scarcely blame any car for boiling. OY. | ||
