When the brakes are bled manually, fluid comes out at all 4 corners , =
just like when the power bleeder is used.
I have had the MC off to check the travel of the actuating rod inside =
the booster, it seems to have adequate travel.
I have also checked the linkage from the pedal to the booster, it is =
fine also.

Jeffery,
Two MC's in a row can't be bad, can they?
When you pump the brakes manually does any fluid come out of the =
bleeder?
If no, I would say take the MC off and look in the booster and verify =
that the stroke rod is there. Have some press the pedal slowly and see =
if it is moving.
If the pedal just flops to the floor with no resistance is the pin =
that attaches the stroker rod to the pedal busted. =20
Just a thiught and some thing to look at. HTH

Subject: Brake problems in a 16v Conversion (85 Cabriolet)
I am in need of some brake diagnosis help. The car in question =
is a 1985 Cabriolet with a full 16v conversion- motor, tranny, all =
wiring, brakes, MC, booster, pedal cluster, rear disk axle beam, =
exhaust, etc. Esentially it is a complete Scirocco 16v transplanted into =
a Cabriolet.
The brakes have no pedal - it goes all the way to the floor. The =
front brakes are off of a running/driving 16v Scirocco (new pads, and =
rotors), the rear is a scirocco axle beam, and A3 calipers (brand new, =
new pads, new rotors, etc). The car also has a new 22mm Corrado MC. I =
first tried bleeding the brakes with my Motive power bleeder- starting =
at the rear PS, with the A3 caliper removed from the stub axle so that I =
could bleed it with the nipple facing corrrectly, as not to induce air =
into the system. from there moving on to the DS rear, PS front, and then =
DS front. The brakes bleed great, all air seems to be evacuated, and =
then when I get in the car....WTF?!?!? no pedal. I tried replacing the =
MC with another new one (this time a german ATE instead of an Italian =
made one), to the same result. I tried replacing the booster with =
another, same result. Always bleeds fine, but still no pedal. I have =
even tried bleeding it manually, but no go. I used all new or known good =
parts to avoid problems, but no luck. I even connected all the lines =
without the proportioning valves , just to see if it made any =
difference. I would appreciate any and all input on the matter, as I =
would really like to get the car out of my garage to move another =
project inside.....(1988 Scirocco 16v , 47k original miles, white, no =
sunroof, manual window/lock, cloth /vinyl, 1 lady owner, =
nonsmoker....)......help please. I can make em run, just not having much =
luck in stopping this thing....
