TL;DR: This book is a single source of information on all essential concepts, guidelines and design checks required for designing safer brakes.
Abstract: The objectives of this third edition of an SAE classic title are to provide readers with the basic theoretical fundamentals and analytical tools necessary to design braking systems for passenger vehicles and trucks that comply with safety standards, minimize consumer complaints, and perform safely and efficiently before and while electronic brake controls become active. This book, written for students, engineers, forensic experts, and brake technicians, provides readers with theoretical knowledge of braking physics, and offers numerous illustrations and equations that make the information easy to understand and apply. New to this edition are expanded chapters on: • Thermal analysis of automotive brakes • Analysis of hydraulic brake systems • Single vehicle braking dynamics

TL;DR: In this paper, a fluid pressure operated motor for hydraulic booster brake mechanisms was proposed and used to operate a vehicle's master cylinder, where the displacement of fluid from a vehicle master cylinder is utilized for operating the booster brake.
Abstract: This invention relates to hydraulic booster brake mechanisms and more particularly a fluid pressure operated motor for use with such mechanisms. Several types of booster brake mechanisms have been developed wherein the displacement of fluid from a vehicle master cylinder is utilized for operating...

TL;DR: In this article, the holding piston is represented as a differential differential piston, and the second ring surface of the differential piston is defined as a blockable hydraulic chamber, and a piston effect in the second chamber corresponds to a force that acts counter to the direction of actuation on the hold piston.
Abstract: A brake system includes a main brake cylinder and a pedal decoupling unit provided with a holding piston, the first ring surface thereof together with a first primary brake cylinder piston defining a first hydraulic chamber that is hydraulically pressurized with an electrically controllable pressure supply device. In order to improve the pedal characteristics of the brake system, in particular in a brake-by-wire brake system, the holding piston is embodied as a differential piston, the second ring surface thereof defining a second, blockable hydraulic chamber, and a piston effect in the second chamber corresponds to a force that acts counter to the direction of actuation on the holding piston.

TL;DR: In this article, a hydraulically actuated brake system for vehicles, comprising a hydraulic pump (18), a high pressure hydraulic accumulator (24) for a powershifted brake system (10) and a conventional master brake cylinder (10), is described.
Abstract: The present invention relates to a hydraulically actuated brake system for vehicles, comprising a hydraulic pump (18), a high pressure hydraulic accumulator (24) for a powershifted brake system (10) and a conventional master brake cylinder (10) used to indicate the prescribed braking force value. The invention suggests that a suction part of the hydraulic pump (18) be connected to a low pressure hydraulic accumulator (20) into which the brake fluid flows from the wheel brake cylinders (16) when the wheel brake pressure goes down. The advantage of the inventive system is that it makes useless the connections from the hydraulic pump (18) to a holding tank (12) of the master brake cylinder (10), which are likely, in case of sealing defect, to bring about a malfunction of both the powershifted brake system and the auxiliary manually actuated brake system.
