Sloughing means degradation of a brake cup as evidenced by the presence of carbon black loosely held on the brake cup surface, such that a visible black streak is produced when the cup, with a 500 ☑0 gram deadweight on it, is drawn base down over a sheet of white bond paper placed on a firm flat surface. Scuffing means a visible erosion of a portion of the outer surface of a brake cup.Ī silicone base brake fluid (SBBF) is a brake fluid which consists of not less than 70 percent by weight of a diorgano polysiloxane. Packaged lot is that quantity of brake fluid shipped by the manufacturer to the packager in a single container, or that quantity of brake fluid manufactured by a single plant run of 24 hours or less, through the same processing equipment and with no change in ingredients. Packager means any person who fills containers with brake fluid that are subsequently distributed for retail sale. Hydraulic system mineral oil means a mineral-oil-based fluid designed for use in motor vehicle hydraulic brake systems in which the fluid is not in contact with components made of SBR, EPR or NR. In addition, S5.3 applies to passenger cars, multipurpose passenger vehicles, trucks, buses, trailers, and motorcycles.īlister means a cavity or sac on the surface of a brake cup.īrake fluid means a liquid designed for use in a motor vehicle hydraulic brake system in which it will contact elastomeric components made of styrene and butadiene rubber (SBR), ethylene and propylene rubber (EPR), polychloroprene (CR) brake hose inner tube stock or natural rubber (NR).Ĭhipping means a condition in which small pieces are missing from the outer surface of a brake cup.ĭuplicate samples means two samples of brake fluid taken from a single packaged lot and tested simultaneously. This standard applies to all fluid for use in hydraulic brake systems of motor vehicles. The purpose of this standard is to reduce failures in the hydraulic braking systems of motor vehicles which may occur because of the manufacture or use of improper or contaminated fluid. This standard specifies requirements for fluids for use in hydraulic brake systems of motor vehicles, containers for these fluids, and labeling of the containers.
