My goodness guys and gals. I have been smitten by the infamous resevoir tank dilema.
After reading numerous threads on the brake problems, one of the 'rude awakening' items refered to the resevoir and it's many partitons.
I have found that this is quite relevant, in that during the bench bleed I had to physically hold the MC off level, rocking front to back etc, to get the fluid into the rear partition. Then bench bleed went off without a hitch. After installation, it was paramount to monitor this tank partition (which is hidden if you are standing on the driver side of the booster), and required 'topping off' after each wheel was bled. The rear partition will go down to 'min' but the larger front partition will show 'max'.
However, what is wisdom, but to make mistakes and learn from them.
I am a much wiser and well informed SEL jocky again.
Thanks to all that helped.
Joe
