§ 1245. Brakes--All Vehicles.
(a) Reciprocating Compressor Discharge Line--Every part of the first 24-inch length of a reciprocating air compressor discharge line, measured from the compressor discharge port, shall be designed to withstand at least 450 degrees Fahrenheit for continuous service and, if flexible hose, shall be reinforced by at least one layer of wire braid. The entire air discharge line and its couplings shall show no leakage under a pressure of 200 pounds per square inch for 5 minutes. This provision does not apply to school buses manufactured prior to January 1, 1968, or to vehicles manufactured on and after March 1, 1975, in compliance with FMVSS 121 (49 CFR 571.121).
(b) Check Valves--Motor vehicles equipped with a check valve in compliance with Vehicle Code Sections 26507 and 26522 shall have a readily accessible means for testing proper operation of the valve, and tools needed for the test shall be carried in the vehicle. The means shall not consist of loosening any connection between the source of compressed air or vacuum and the check valve. This provision does not apply to Type 1 school buses manufactured prior to January 2, 1968.
(c) Air Reservoirs--Property-carrying vehicles first sold and registered after January 1, 1967, school buses, farm labor vehicles, and Type 1 buses, equipped with air or vacuum brakes, shall have a reserve capacity sufficient to ensure a full service brake application with the engine stopped without depleting the air pressure or vacuum below 70 percent of that indicated by a gauge immediately before the brake application. Such vehicles manufactured on and after March 1, 1975, and equipped with air brakes shall have a reserve capacity sufficient to ensure a full brake application with the engine stopped without depleting the air pressure below 85 percent of that indicated by a gauge immediately before the application.
(1) Air Reservoir Specifications--Air brake reservoirs installed as original equipment on vehicles manufactured in compliance with FMVSS 121 (49 CFR 571.121) are not required to be marked. Replacement air brake reservoirs shall met SAE J10 in the 1965 or later edition of the SAE Handbook and be marked with the manufacturer's initials followed by “SAE J10 150 psi Rated Working Pressure” and the date of manufacture. Auxiliary air tanks shall meet the requirements of Section 1252 of this title.
(d) Air Flow Restriction--Any valve or other mechanism of an air brake system that restricts the free flow of compressed air between the brake application control and the brake actuators at application pressures above 10 pounds per square inch under normal operating conditions shall comply with the brake equipment requirements in Article 12, Chapter 4, of this title, beginning with Section 1061, except as provided in Vehicle Code Section 26311(b) governing reduced braking effort on front wheels.
(1) On vehicles manufactured after July 1, 1992, and on any replacements made to the brake line on any vehicle after this date, nonmetallic (plastic) brake tubing shall only be used where relative movement does not occur or through an articulation point provided movement is less than 4.5 degrees in a vertical plane and 7.4 degrees in a transverse horizontal plane. Plastic tubing shall not touch or be attached to leaf, coil, or air suspension springs.
(2) Brake Hose and Coiled Nonmetallic Tubing--Brake hose and coiled nonmetallic brake tubing is for use where substantial relative movement in the line occurs or the line is exposed to potential tension or impact such as between the frame and axle in a conventional suspension system. Only coiled nonmetallic brake tubing or brake hose may be used for connections between towed and towing vehicles or between the frame of a towed vehicle and the sliding subframe of an adjustable axle of that vehicle. If coiled nonmetallic brake tubing is used in these locations it shall be encased in a spring guard or similar device which resists kinking of the tubing at the fittings to which it is attached.
(i) Air Brake Tubing Standards--Air brake tubing that is original equipment on a vehicle at time of manufacture is not required by FMVSS to meet any requirement but is subject to National Highway Traffic Safety Administration (NHTSA) recall if it become a safety defect. Replacement brake tubing installed on or after July 1, 1992, shall meet the following Society of Automotive Engineers Standards:
(2) Nonmetallic Tubing--Nonmetallic tubing shall meet SAE J844, Nonmetallic Air Brake System Tubing, Type B (reinforced). Such tubing shall be identified in contrasting color with the markings “Airbrake, SAE J844 Type B,” the nominal outside diameter of the tubing in inches, and the tubing manufacturer's name or symbol.
(2) Brake Hose--Air, hydraulic, and vacuum brake hose manufactured on or after September 1, 1974, shall be marked in letters at least ⅛ inch high with “DOT”, the hose manufacturer's designation, the month and year of manufacture, and the nominal inside diameter of the hose. FMVSS 106 does not require these markings to be visible on a completed brake hose assembly.
(3) Replacement Air Brake Hose Assemblies--Replacement air brake hose assemblies manufactured on or after September 1, 1974, with end fittings attached to the hose by crimping or swaging shall have at least one end fitting etched, stamped, or embossed with a designation at least 1/16 inch high that identifies the hose assembly manufacturer.
(4) Air Brake Hose Fittings--Air brake hose fittings manufactured on or after September 1, 1974, that are not crimped or swaged shall have at least one component etched, stamped, or embossed in block capital letters, numerals, or symbols at least 1/16 inch high with “DOT”, a designation that identifies the manufacturer of that component of the fittings, “A” for nonreusable fittings at “AI” or “AII” for reusable fittings, and the nominal inside diameter in inches or millimeters (or outside diameter of plastic tubing) to which the fitting is properly attached.
(5) Hydraulic Brake Hose Assemblies--Hydraulic brake hose assemblies manufactured on and after September 1, 1974, shall have at least one end fitting etched, stamped, or embossed with a designation at least 1/16 inch high that identifies the manufacturer of the assembly. Each hose shall have at least two clearly identifiable stripes at least 1/16 inch wide placed on opposite sides of the hose parallel to its longitudinal axis, except where the end fittings prevent its installation in a twisted orientation on either side of the vehicle.
(6) Vacuum Brake Hose Assemblies--Vacuum brake hose assemblies manufactured on or after September 1, 1974, with end fittings that are attached to the hose by crimping or swaging, or to plastic tubing by heat shrinking or interference fit, shall have at least one end fitting etched, stamped, or embossed with a designation at least 1/16 inch high that identifies the manufacturer of the assembly.
2 pounds per square inch per minute for single vehicles,
3 pounds per square inch per minute for combinations of two vehicles, and
5 pounds per square inch per minute for combinations of three or more vehicles.
3 pounds per square inch per minute for single vehicles,
4 pounds per square inch per minute for combinations of two vehicles, and
6 pounds per square inch per minute for combinations of three or more vehicles.
