Auto Park J72 Question

[71_340]

My RV has the "improved" J72 park brake, it works fine and holds the RV as it is supposed to. It also releases just fine.

My questions is if it is normal that the pump cycles several times while I am sitting a stop light (that is the only time I can hear it, I am sure it does while in motion).

I know how the system works and I am wondering if that condition is normal or if the solenoid valve has to much internal leakage and let the pressure bleed off.

Thanks

Nobody with a 2005 and up P32 Workhorse chassis around here?

I have a 2004 sightseer NO that condition is not normal sounds like a internal leak or the RGS leaking.
