Stating that the problem of deceleration is just as important and necessary of solution as is the one of providing car-acceleration ability, the author gives a comprehensive survey of present braking practice and outlines future requirements and possibilities.
Design factors are considered at length, as well as the subject of what constitutes uniform and effective braking-power, various illustrations and descriptions being included of different types of brake. Brake-actuating means, the calculation of brake-drum size, car-stoppage ability, brake equalizers and brake-linings are commented upon in some detail.
The future of brakes is discussed with reference to the use of the engine as a brake, four-wheel and front-wheel brakes, the servo principle of brake operation and various novel braking methods. A brief summary of what is considered good practice with regard to truck brakes is appended.
