I did. Although on my car's PDWA there is no need to remove the end
caps, the switch provides all the access needed to manually reposition
the piston. I don't know how the various cars' PDWAs vary in design so
perhaps this is not universally applicable. Nonetheless...
I just unscrew the switch from the PDWA's body and using a suitable
pointed instrument gently prod the piston into its centralized position.
Takes all of 5 minutes (even the first time I did it). Much less
frustrating than trying to do it by bleeding I think.
Check out http://www.vtr.org/maintain/pdwa.html for a good description
of the PDWA and to get an idea of what the piston which needs to "gently
prodded" looks like.
Good luck,
