I have a simlar problem with my 1990 Dodge Dynasty, 3.3 L V6, Bosch III ABS. In the Chilton manual, it says 1. Depressurize the accumulator (depress the brake pedal many times with the ignition OFF until pedal pressure feels different--it will get much harder). It takes me about thirty strokes, but Chilton says do 50 just for safety's sake. 2. Connect bleed hose with catch-container to caliper bleed screw. 3. Pump the brake pedal slowly 2 or 3 times and hold it down. 4. With pressure still on the pedal, open the bleed screw at the caliper and allow fluid to flow until pressure is relieved completely. Tighten bleed screw. Repeat with each caliper in this order: left rear, right rear, left front, right front. Hopefully, this will work for you, but after performing this twice, it hasn't eliminated the springy feel at the bottom of the pedal travel for me. I don't think, at this point that my problem is an air bubble, because the brakes are firm (no springiness, no fade) when the accumulator is discharged. I am faced with the $1,100 repair bill (which I paid 110, 000 miles ago for the same problem). Now the car isn't worth that much.
The brake pedal has nothing to do with it. If air is in the system then bleed the brakes.

Air in system. Top off the Master Cylinder and bleed the system to remove any trapped air.
No, as long as your pedal seemed good before the brake job, and you do not loosen the bleeder at all, you do not have to bleed the brakes.
To bleed the brakes on a 1973 Dodge Challenger, start by ensuring the brake fluid reservoir is full. Begin with the wheel farthest from the master cylinder, typically the right rear, and have an assistant pump the brake pedal several times and hold it down. While they hold the pedal, open the bleeder valve on the brake caliper to release air and fluid, then close the valve before they release the pedal. Repeat this process in the order of right rear, left rear, right front, and left front, checking the fluid level regularly.
Air trapped in the brake lines. Bleed your brakes and that will solve the problem.
Air in the brake system. Bleed the brakes again.
Air in the brake system. You need to bleed the air out of the system.
If you are following the proper procedures then the fluid will come out. Have someone pump and hold the brake pedal down, open the bleed screw on the caliper, pressure will force the fluid and air out.
Soft pedal is caused by air in the system. Bleed the brakes starting at RR, then LR, RF, and ending at LF.
Check the brake light switch on the brake pedal
