[TR] TR6 PWDA leak

[acekraut11 at aol.com]

 Mark,

If you go to the Buckeye Triumphs web site they show a nice exploded view of
the part.

Go here:

http://buckeyetriumphs.org/technical/Brakes/MCPDWA/MC.htm

Scroll down the page and you will see a picture of the piston and see where
the O rings sit.  There is no sealing that is supposed to happen with the
switch that screws into the top as it is not supposed to have any fluid in
that part of the PDWA.  Replacing the O rings will make it dry again.  Not my
best job of explaining things coherently but the link above does a much better
job.

Cheers,

Aaron

I'm seeing silicone brake fluid leaking from my PWDA. It is coming up from
the
well surrounding the electrical contacts on the switch housing. This is with
the car just sitting there. I clear it off and it is back filled up the next
morning. Is this indicative of finished o-rings on the PWDA shuttle, or the
switch housing itself? Reparable? The switch is $50 from TRF while the body
of
the unit is unavailable. It still seems to work (I guess no light is good). I
like to keep my original parts if at all possible.
