ok i have a vac brake set up on the t.
new pads rotors etc..
i went thru 1 1/2 bottles of brake fluid bleeding them
\still barely any stopping power.
engine off i can push about 3/4 of the way down after the power assist is gone
does this mean more bleding?
i start with left rear the right rear then right front an finaly left front..
an i doing this correctly?

How are you bleeding them? The only real success I have had is with two people, one operating the brake pedal under the instruction of the person operating the bleeder valve.
-
right rear before the left rear....(passenger side before driver's side)
-
New master cylinder? Did you depress the button on the proportioning valve?
-
there is no need to depress the button on our generation of cars...in fact, it is already depressed and comes out when you step on the brakes...

I found when I had an issue years back that Gravity Bleeding worked great. Also double check the adjustment on the rears & make sure the fronts are working properly with no tears in the rubber seals. My fronts were a little rough looking so I just grabbed new ones for under a $100 total. They also give back a credit for the old cores.
