i have having a problem with my 74 duster brakes i bleed the brake couple of time and the pled still go two the ground. i have swap out rear end and change the master cylinder that came with the rear end but still having the problem. not sure what i am doing wrong

Put a small diameter clear plastic tubing on the end of the bleeder valve, then put a small amount of brake fluid in the bottom of a clear glass bottle. With the open end of the tube in the fluid, you open the bleeder valve and pump the pedal until you have no bubbles of air in the tube. Close the bleeder and move to the other side. You must check the fluid level often in the master cylinder while doing this.

check your front hardware i had a bad spring that was giving me a low pedal, check the wheel cylinders too. try taping them with a wrench to get any little air pockets out of them

Bleeding sequence:
Start with right rear, pass fluid until bubbles stop showing.
2. left rear.
3. right front.
4. left front.

Don’t let the master cylinder go dry during bleeding, keep topping it up as you go, or it will suck more air into the lines. Also you have to pre bleed the master cylinder before attaching the lines to it.

Sometimes rebuilt master cylinders just don’t work, and they will blow by allowing your peddle to go to the floor. Personally I don’t trust the darn things. If you can, spend a few extra bucks and get a new unit.
