TROUBLESHOOTING PROCEDURE
TRAILER BRAKES GRAB WHEN APPLIED
STEP 1
Does test equipment pass offset test?
WARNING
If air lines are disconnected when they are under 125± 5 psi (862± 34 kPa) pressure, they
can whip around. Care should be exercised when disconnecting an air hose that is thought
to be under pressure. Be sure to wear proper eye protection. Failure to comply may result in
injury or death to personnel.
NOTE
•
Air lines and valves listed in this troubleshooting procedure are illustrated and located
in Air System Schematic.
•
When rod is disconnected from the valve, it should hang freely without interference
from other components. During testing of load sensing valve, control rod must be
able to simulate a no load condition.
