RE: Recentering the brake failure pin

["Eppinger.Michael" <Eppinger.Michael@domain.elided>]

When you recenter the sensor, you need to remove it from the proportioning
body, otherwise you will shear the sensor pin.  This will not introduce air
into the system when you recenter due to the o ring seals.  Once you fix the
cause of the pressure differential, remove the sensor and apply the brakes.
This will cause the "trigger" inside the proportioning valve to recenter,
then reinstall the sensor.  If this is confusing, the manuals cover this
proceedure quite well.

Hope this helps
