Reid, I just checked and the part that is different to the pictures is liek you
from the MC to the PDWA. Rear cylinder to front brakes. I suppose that the
pictures are "artists impressions". Until I do the same as you and get the
rebuild done on the brake system I won't know if I have the same problem or not.
It should not matter which is which as the PDWA senses which side has failed (or
thinks it has by the pressure differential.)
Maybe someone else knows of if once it has been triggered, does it block the
flow to that side of the device. I have seen all these articles about centering
it. If it is like a valve then there is the potential that it could block the
fluid flow and that's the reason for the poor bleeding of the front brakes.
