Funny that I am told there is no adjustment. I remember when I
installed the new booster that it mentioned a factory setting and
something about possibly needing to change it, am pretty sure it
involved rotating the yoke which connects to the brake pedal. Lost
the little installation instruction sheet that came with
it...otherwise I would re-check that. I don't even know how far away
from the shuttle valve the front end of the pushrod is with brake not
depressed. But if it has to move forward a half inch before even
touching it, then obviously the car is going to have a lot of brake
Anything further you can tell me on getting the brakes properly
bled would be appreciated.
There was a "benck-bleed" procedure given for installation of the new
master cylinder. I did it exactly as stated, got the master cylinder
completely full/bled. But it was a waste of time! Reason is that
obviously I have to take the two plugs off the botttom ports and the
two fittings with tubing off the other two ports before I can
reconnect the brake lines...and so flud leaks out massively and air
Guess I will jack the car in the morning to see if one half of the
brakes is not working.
