* 3.4.11 Brakes. Brakes shall conform to Federal Motor Carrier Safety Regulations

393.40 through 393.43 and 393.45 through 393.52. Parking brakes shall be furnished. Brake

linings shall be of nonaebestos material.

3.4.11.1 Power-hydraulic type. Class 16 vehicles shall be equipped with power assisted, hydraulically actuated, four-wheel service brakes or with full air brakes on all wheels.

3.4.11.1.1 Split hydraulic brake system. The power-hydraulic brake system shall be so arranged as to provide separate systems for at least two wheels and so designed and constructed that rupture or leakage type failure of any single pressure component of the service brake system, except structural failures of the brake master cylinder body, effectiveness indicator body, or

other housing common to the divided system, will not result in complete loss of function of the

vehicle brakes when force on the brake pedal is continued. "Pressure component" means any internal component of the brake master cylinder or master control unit, wheel brake cylinder, brake line, brake hose, or equivalent, except power assist components.

3.4.11.1.2 Indicator light. The split hydraulic brake system shall be equipped with an electrically operated red light mounted on the instrument panel to indicate system effectiveness. The light shall have an area of not less than 0.196 square inch. It shall illuminate before or upon application of the brakes when an actuating-pressure component of the system has sustained a loss of pressure. The indicator light system shall include a means for testing by the vehicle operator to assure that the light bulb is operable.

* 3.4.11.2 Air brakes. Class 19, 28, 34.5, 36, 44 and 50 vehicles shall be equipped with full air brakes on all wheels. The braking system, complete with all necessary components, shall include:

(a) Air compressor, unloader-head type, engine driven and engine lubricated, air- or water-cooled, and having a capacity of not less than 7.25 cubic feet per minute (cfm) for class 16, 19 and 28 vehicles and 12 cfm for class 34.5, 36, 44 and 50 vehicles

(b) Air storage reservoir(s), each tank equipped with drain, and with safety and check

valves between compressor and last reservoir tank. When a pneumatic fuel product tank control system is furnished, the air storage reservoir(s) shall be of sufficient capacity to supply air for both the air brake system and the complete tank

pneumatic control system.

(d) Air control valves

(e) Low air pressure warning, visible and audible

(f) Service brake stop lamp switch

(g) Automatic moisture ejector
