This SAE Standard covers molded rubber boots used as end closures on drum-type wheel brake actuating cylinders to prevent the entrance of dirt and moisture, which could cause corrosion and otherwise impair wheel brake operation. The document includes performance tests of brake cylinder boots of both plain and insert types under specified conditions and does not include requirements relating to chemical composition, tensile strength, or elongation of the rubber compound. Further, it does not cover the strength of the adhesion of rubber to the insert material where an insert is used. The rubber material used in these boots is classified as suitable for operation in a temperature range of -40 to +120 degrees C +/-2 degrees C (-40 to +248 degrees F +/-3.6 degrees F).

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 with fluids meeting SAE J 1703 are not known to have any adverse effects on performance, but all combinations have not been tested.

The scope of the test method is to provide stakeholders including fluid manufacturers, brake manufacturers, aircraft constructors, aircraft operators and airworthiness authorities with a relative assessment of the effect of deicing chemicals on carbon oxidation. This test is designed to assess the relative effects of runway deicing chemicals by measuring mass change of contaminated and bare carbon samples tested under the same conditions.

The focus of this SAE Aerospace Standard (AS) is the integration of thermally actuated pressure release devices, hereafter referred to as fuse plugs, with the wheel and brake assembly. It does not address the manufacturing, quality or acceptance test requirements pertaining to the production of these fuse plugs. It establishes minimum design, installation, qualification, and operational requirements for fuse plugs which are used only in tubeless tire type aircraft braked wheels. Fuse plugs are designed to completely release the contained inflation pressure from a tubeless tire and wheel assembly when brake generated heat causes the tire or wheel to exceed a safe temperature level. The objective is to prevent tire or wheel rupture due to brake generated heat that could cause an unsafe condition for personnel or the aircraft.

This SAE Recommended Practice is intended to provide a uniform means of identification which may be used to classify the friction coefficient of brake linings, based on data obtained from tests conducted in accordance with SAE J661 Brake Lining Quality Test Procedure and SAE J2975 Measurement of Copper and other elements in Brake Friction Materials. NOTE: It is emphasized that this document does not establish friction requirements for brake linings, nor does it designate significant characteristics of brake linings which must be considered in overall brake performance. Due to other factors that include brake system design and operating environment, the friction codes obtained from this document cannot reliably be used to predict brake system performance.

This SAE Recommended Practice establishes a uniform procedure for testing the brake systems (service and parking) of all passenger cars, light-duty trucks, and multipurpose passenger vehicles up to and including 4500 kg (10 000 lb) GVWR. The purpose of the test code is to evaluate brake system performance of vehicles in service for compliance with regulations. The test code is expected to be utilized as a basis for a brake evaluation conducted by State or Federal officials engaged in highway safety programs. The primary consideration is that this test requires a minimum of instrumentation, time, driver skill, and cost to conduct.

This SAE Recommended Practice establishes a method of evaluating the structural integrity of the entire brake system of all passenger cars under extreme braking conditions. The main purpose of this document is to evaluate the structural integrity of a vehicle's braking system. However, other areas, such as the steering or suspension system, may also be evaluated during the test, providing that the criteria and procedure detailed in the following sections are not modified in any way. For repeatability, it is recommended that a brake apply device be utilized whenever possible, since it will eliminate the variations in application times and efforts of different operators.

There is currently no requirement in place for aftermarket brake lining performance. NHTSA has indicated that the automotive aftermarket should take a proactive approach to come up with a standard test definition for lining evaluation. Many aftermarket manufacturers use dynamometer testing to evaluate lining performance, but there is currently not a common recognized method for on-vehicle lining screening. This procedure was created to provide a quick, on-vehicle test method for lining performance evaluation. This procedure is intended for use in passenger cars; multi purpose vehicles and light trucks with a gross vehicle weight less than 4535 kg(10 000 lb).

This SAE Information Report establishes a minimum level of uniform recipes for contaminants which may be used when durability testing pneumatic components to obtain additional information on how a device may perform under more true to-life operating conditions. This type of contamination testing, however, is not meant to replace the type of performance testing described in SAE J1409 and SAE J1410. Durability testing in the presence of contamination, however, will yield results more reflective of actual in-service field conditions and provide an additional evaluation of pneumatic devices. While the contaminant supply rate and other test criteria of the device being tested must be set by the device manufacturer or user, the items covered in this document will be: 1.1 Formula for contaminated oil to be used as a lubricant when testing air compressors. 1.2 Formula for a contaminant to be used when testing pneumatic system components other than air compressors. 1.3 Other contaminants.
