Did you replace the rubber brake hoses? If not and they are original...there
could be an internal obstruction or breakdown of the interior hose wall. ...
a flap breaks loose and won't let the fluid past.. or the hose is
constricted somehow. I would replace all the rubber brake hoses and then
rebleed the system. Also check for mashed rigid lines and blocked (choked
with rust, etc) bleeder screws.
The PWDA is only a warning system...it illuminates when the one of the
systems (either front or back) fails.
