PDWA warning switch leak

[Greg Perry <rgperry@earthlink.net>]

Hello,

My PDWA warning switch is leaking (overflows) brake fluid from inside the the 
female connector over time.  Since there is not an o-ring or gasket on the 
switch or the mating surface of the PDWA valve, is the space between the switch 
and the internal piston of the PDWA valve supposed to be full of brake fluid? 
Basically do I need to rebuild the PDWA valve or just replace the warning 
switch?

Thanks,
