Brake System Preventive Maintenance WARNING! Do not operate the vehicle in the event of a malfunction in any air or hydraulic circuit. Such a malfunction may prevent the brake system from operating properly, and could result in an accident causing death or serious personal injury. The vehicle should not be operated until the system is repaired and both braking circuits, including all pneumatic, hydraulic, and mechanical components are working properly. – 194 – Y53-6027 Medium Duty (R05/09)
Preventive Maintenance Introduction AIR SYSTEM WARNING! Prior to the removal of any air system component, always block and hold the vehicle by a secure means other than the vehicle's own brakes. Depleting air system pressure may cause the vehicle to roll unexpectedly resulting in an accident causing death or injuries. Keep hands away from chamber push rods and slack adjusters, they may apply as system pressure drops. • Never connect or disconnect a hose or line containing air pressure. It may whip as air escapes. Never remove a component or pipe plug unless you are certain all system pressure has been depleted. • Never exceed recommended air pressure and always wear safety glasses when working with air pressure. Never look into air jets or direct them at anyone. • Never attempt to disassemble a component until you have read and understood recommended procedures. Some components contain powerful springs and injury or death Air System can result if not properly disassembled. Use only proper tools and observe all precautions pertaining to the use of those tools. • Completely bypassing a Bendix AD-IS air dryer will bypass the system’s pressure protection valves. This could lead to loss of air pressure or damage to the vehicle’s air system, which could cause an accident involving death or personal injury. Always adhere to the manufacturer’s procedure if it is necessary in an emergency to temporarily bypass an AD-IS-series air dryer. WARNING! Do not release the parking brake or attempt to move the vehicle until air pressure in both circuits is at least 100 psi (690 kPa), the level required for normal brake operation. • Do not use the trailer hand brake control to hold vehicle while parked. This control utilizes air pressure for brake application. Because acceptable air leakage levels cause all truck air systems to gradually lose pressure, vehicle rollaway could occur, resulting in an accident and death or injuries. • Always apply the tractor and trailer parking brakes when the vehicle is unattended.
