Dr. P. -C. i Stanley, chief ;. engln ;er bt th$fUrjest .manufacturer f asbestos ' brake lining. in; the vorldjn writing on the subject of rakea and braking for tbe Na lonSl Safety News, says:'1,-: "The efficiency of automobile ) rakes depends upon (1)' the pressure applied to, the pedal; , ( 2i he ngechanlcab advantage c of the ippllqation;: (3) the diameter of :he brake drum; (4) the coeffi cient of friction of the lining; and (6) tfie adjustment of the brakes; "Fdur jwheel brakes, ,wheu ful y efficient,, will cat doWnstop plng distances" full jr 5 0 ' per ceht; tut . four wheel brakes, . like, all other! ' are often far below their aximum. in efficiency. Taking p iistMeir order the factors in rake efficiency mentioned, the oUowtngcdrnment will be suffi- jciently explanatory: , t "(1) The pressure which can be applied to the brake pedal var- Jes with the weight and. strength kf the driver; but no - person should drive a car on which he is unable to lock both rear wheels by pressure on the pedal in emer gency. .... "(2) The mechanical advan tage of the application may . be measured by the ratio of the ped al travel to the average Clearance between brake lining and 'drum. In some cases this is as high as 120.1 which means that one pound of pressure on the pedal will in theory apply aa s average pressure of 120 pounds , between the lining and the druffi This high efficiency is diminished, of course, by friction, which Isv gen erally increased greatly by. lack of lubrication and by rusting,, , . "(3) The larger the diameter of the brake drum, the more ef fective is the pressure applied to it. Drum diameters are --limited by wheel sizes, and these are gen erally reduced by the general use of balloon tires. "(4) The coefficient of fric tion of the Brake lining when dry and free from oil is .4 to .6, which means that from .4 to .0 of.-the pressure applied to it will" be ef fective, in retarding the. rotation of the brake drum. The efficien cy of the lining is greatly reduced by a film of reasei oil or, water. The water film may be destroyed by applying the brakes, but an oil or frrease film is , found -. al most Impossible, to com pleteljr re move. - " ( 5 ) The normal efficiency of pavement Is but , under some conditions fails as low as .5; ,We must realize that all braking ef ficiency depends on the friction between the tire and pavement, and therefore we will .' reduce speed when the character ef the pavement Is unknown., "(6) By braking adjustment, we mean particularly the setting of the bands or shoes to an even and proper clearance between lin ing and drum. This clearance in creases as the Untax wears, and need for adjustment Is discovered by the fact that the pedal must be pushed to the floor board to obtain efficient braking. All ad justments should benade on the adjustment screws on the brakes. never on the pull rods. Shorten ing pull rods decreases mechani cal advantage. 'The one test of brake effi ciency which every driver can make has already been pointed out. This Is the ability quickly to lock both rear wheels by pushing on the pedal: If unable to d so when braking an. emergency stop. Ha brakes need attention. . I do not advocate locking wheels in this manner as a regular practice, hut it reoresents maximum effi ciency. "Whim brakes are unequal In efficiency, they become less ef fective and more dangerous. They Increase the tendency Jte said. Eoualiiation is usually tested by comparing the lengths of marks made on the pavement py locaea .1,1.

Oviiers report that it is quite th ordinary thing to average 40 miles an hour over trips up to 400 tff 450 miles in a day which means I that much driving is done .well over the sixty mile an hour mark. ; In; this respect, the American built, Willys-Knight is the coun terpart of the European: Knight: motored cars which have set and heJd many of the most, important Continental speed records : f or stock' cars.- ; ', V;.". According to? the local repre sentative, the construction of the Knight sleeve valve motor adapts itself particularly w ill ' lor high speed performaoice. "The action of the sleeves in itself is proof; against .'the usual feeling . of' . ssvero motor ' strain under long, sustained high speed," he says. "Many drivers do not feel that they want to keep the motor of their car "? turning over at a high rate of speed because they do not like gine. The Wilys-Knight " owner never has this feeling, for at high speeds as well as at moderate speeds the power plant operates with convincing smoothness and silence.. ..u't'' -V' he"operatIon of the valve mechaiis.m Is through .two con necting' rodtf in 'eacti -cylinder, each one lifting and-loweriagl a sleeve aa ;tBe ijtoslejeves sliding hy each other for an inlii-to open and close the intake and exhaust ports..
