Pretty sure that's wrong.
See http://www.vtr.org/maintain/pdwa.shtml - the piston is a constant
diameter. How would it shut off flow, without some careful positioning
of the o-ring, which shouldn't easily seal a round hole in the side of
the bore anyway.
Some look different: http://www.74tr6.com/pdwa.htm But I still don't
think it's made well enough to seal against brake pressure.
I've had my PDWA illuminate many a time on my old Spitfire, and I never
had any diminution of brakes. Doesn't seem safe to cut off half your
brakes for a small leak...
