I have a 1980 datsun 1200 ldv have replaced the master cylinder Bled all 4 wheels.Pedal stays low +_ 10 mm from floorboard Do not find air in the system had adjusted all 4 wheels brakes thanks
Did you properly bench bleed the master cylinder itself before installing? It must be bled or there will be air trapped inside the master cylinder itself that no amount of wheel bleeding will remove.
If there is truly no air in the lines, I would 1st check to see that the brake booster has a good vacuum line to it. After that I would adjust the pushrod coming out of your brake booster to your master cylinder.
