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...
