Typically, the problem you describe of the pedal going nearly to the
floor indicates a circuit failure like I described earlier. If the
problem were air in the lines the brakes would engage early in the pedal
travel but would not have much stopping power without significant pedal
travel. Another term for this condition is a "spongy" pedal.
You didn't say you replaced the master cylinder. That is what I would
suspect is the problem. Also, you should verify that each wheel
cylinder or caliper is able to move freely though the full range of
travel. A binding wheel cylinder or caliper will cause the problem you
are experiencing.
Rotors will not cause the problem so don't waste your money there.

Subject: Brake Issues Still
I replaced the propotioning valve with a very nice looking brass one.
To bad
you cannot see it under the brake booster. I am still having issues with
braking. In my driveway going back and forth it seems to force the
front or
rear downward as expected based on the direction that I am going. I
bled the
master, and all lines again. This time I did not pull the pin on the
proportioning valve since I have been told this causes issues. All
lines bled
well with large pockets of air coming out of each wheel. I started at
the
passenger side rear, then drivers side rear, passenger side front and
last the
drivers side front. I bleed an entire large brake fluid bottle of fluid
through the lines. Just trying to be thourough. Whenever I press the
brake it
seems that I end up about a 1/2 inch from the floor to hold the car.
The is
especially true on a down hill stop at a stop sign.
I have replaced the rear drums, the rear cylinders, rear shoes, front
brake
lines, front calipers, front pads, rebuilt the power brake booster and
replaced the porportioning valve. I can replace the rotors but the
really look
fine and seem to be true. I am not feeling anything in the braking that
would
indicate the rotors need to be turned.
Am I missing something?
