🔧 Maintenance Recommendations

A poor-quality brake valve can be the difference between a safe trip and a fatal accident. Valves from brands like Bendix or Wabco undergo extreme fatigue testing that generic parts simply cannot withstand. A leading brand component not only lasts longer but also protects the entire integrity of the braking system.

To maintain this system at 100%:

• Pair these valves with a good air dryer to prevent contamination from damaging the internal seals.
• Regularly inspect connections for pressure leaks
• Replace seals according to the intervals recommended by the manufacturer
• Check the braking system response at each pre-trip inspection

Signs You Need to Replace a Valve:

• Audible air leaks at the valve
• Slow or delayed braking system response
• Loss of air pressure in the system
• Uneven braking between axles
• Valve that does not fully release
• Severe external corrosion

Installation Procedure (General):

• Park on a level surface and apply the parking brake
• Chock the wheels to prevent movement
• Release all air pressure from the system
• Disconnect the air lines from the old valve
• Remove the old valve from the assembly
• Clean the mounting area and connections
• Install the new valve with new seals
• Connect the air lines in the correct order
• Use Teflon tape or appropriate sealant on threads
• Tighten all connections according to specifications
• Rebuild system pressure
• Check for leaks with soapy water
• Test the system's functionality before operating it

Air Brake System Inspection:

• Check the system's build pressure (it should reach 90-125 PSI)
• Inspect all air lines for cracks or damage
• Check all connections for leaks.
• Test the purge valve for proper operation
• Check the braking system response time
• Inspect the air dryer for proper operation

Preventive Maintenance:

• Drain the air tanks daily to remove condensation.
• Inspect for air leaks weekly
• Verify the system response at each pre-trip inspection
• Replace the air dryer cartridge at the recommended intervals.
• Inspect valves for corrosion or damage monthly
• Check the system pressure regularly

Functionality Tests:

• Pressure build test (must reach pressure within specified time)
• Pressure drop test (maximum permissible loss with brakes applied)
• System response test (brake application time)
• Release test (brakes must release completely)
• Low pressure warning test (alarm should activate at 60 PSI)

Pro Tips:

• Use only valves that comply with FMVSS-121
• Document all brake system repairs
• Save the part numbers for future reference.
• Use only clean, dry air in the system
• Replace valves in pairs when possible to maintain balance
• Consider upgrading to ABS technology if you don't already have it.
