Brino, I too would like a copy of your bleed method. I will be bleeding this weekend, using dot 3 non-synthetic.

Just answered my own question this weekend. Brakes did not work much...pedal was very spongy. To my surprise, when I bled the brakes again, more of the old yellow fluid came out, even though it was purple coming out of each corner the first time around.

This time I did not use the brake pedal at all, used the Mighty Vac tool instead. Pedal feels hard now, will take it out another weekend to test.

Oh, by the way, FYI, just because all the websites say the Dorman #13908 bleeder screw is the correct part#, it is NOT even close to what is needed for the older Lockheed wheel cylinders or the orig Delcos.
