Perform function check of automatic linkage adjuster

1

Pressurize the brake system with specified operation pressure. 



2

Using a torque wrench, apply the torque prescribed on the   taper coupling screw of the regulator, acting on the screw counterclockwise.



3

Repeat the process of control three times in each regulator.


Tapered coupling should not slide when applying the torque prescribed in the screw


If the conical coupling slides in a moment of force below the moment prescribed, replace the brake regulator completely.
