Service Maintenance of SAE J1703 and SAE J1704 Brake Fluids in Motor Vehicle Brake SystemsJ1707_202106 (Current)06/10/2021
This SAE Recommended Practice provides basic recommendations for dispensing and handling of SAE J1703 and SAE J1704 Brake Fluids by Service Maintenance Personnel to assure their safe and effective performance when installed in or added to motor vehicle hydraulic brake actuating systems. This document is concerned only with brake fluid and those system parts in contact with it. It describes general maintenance procedures that constitute good practice and that should be employed to help assure a properly functioning brake system. Recommendations that promote safety are emphasized. Specific step-by-step service instructions for brake maintenance on individual makes or models are neither intended nor implied. For these, one should consult the vehicle manufacturer’s service brake maintenance procedures for the particular vehicle. Vehicle manufacturer’s recommendations should always be followed.

Selection of EPDM Elastomer in Brake Hose Application for Improved Brake System Performance2010-01-188510/05/2010
Brake system has been considered as the most important safety system for a vehicle. Performance of the Brake system depends upon various factors like purity of brake fluid, material and construction of rubber hose, rubber seal performance etc. The purity of the brake fluid is one of the most vital factor and incompatibility of the rubber hose with brake fluid causes contamination of the brake fluid. This intern can cause shrinkage / swelling of master, slave cylinder rubber seals. The change in the dimensional of the rubber seals directly affects the performance of the brake system. In order to evaluate the performance of the brake system, Styrene Butadiene Rubber (SBR) and EPDM elastomers with different % of ethylene and varying ENB content were considered for brake fluid compatibility test. These rubber materials were tested in the different brands of DOT 3 brake fluid. Design of experiments has been carried out on EPDM material with different % of ethylene and varying ENB content to

Low Water Tolerant Brake FluidsJ1705_199412 (Historical)12/01/1994
This SAE Recommended Practice was prepared by the Motor Vehicle Brake Fluids Subcommittee of the SAE Hydraulic Brake Systems Actuating Committee to provide engineers, designers, and manufacturers of motor vehicles with a set of minimum performance standards in order to assess the suitability of silicone and other low water tolerant type brake fluids (LWTF) for use in motor vehicle brake systems. These fluids are designed for use in braking systems fitted with rubber cups and seals made from natural rubber (NR), styrene-butadiene rubber (SBR), or a terpolymer of ethylene, propylene, and a diene (EPDM). In the development of the recommended requirements and test procedures contained herein, it is concluded that the LWTFs must be functionally compatible with existing motor vehicle brake fluids conforming to SAE J1703 and with braking systems designed for such fluids. To utilize LWTFs to the fullest advantage, they should not be mixed with other brake fluids. Inadvertent mixtures of LWTFs

Brake Drums — investment for safety and profit60003901/01/1960
CONSIDERATIONS in brake and brake drum rating, design, and testing are: 1. An engineering term to define brake, brake lining, and brake drum heat dissipating ability is necessary. This paper describes one possible term — continuous horsepower. 2. Brake lining material is a current weak link. Unless a major breakthrough in this area is forthcoming, no major strides in reducing both the weight and cost of brake and drum assemblies appears possible. 3. Under the limitations imposed by current materials, the major element not yet sufficiently appreciated by the industry is drum positioning and exposure.*
