Is the brake-light on? I understand what you replaced but what was the procedure that you followed to bleed the brakes? Did you bench bleed the master? After installing the new master, did you bleed air out of the proportioning valve, and all four wheels. You need to start with the F/L wheel and finish with the R/R wheel. Unless you own and are using an automatic brake bleeding unit. You will have to get another person to help bleed them.

Brake pedal to floor have replaced brake pads and master cylinder


Did the pedal go to the floor beforehand? Was the master cylinder leaking, and did you bleed it properly? If the master cylinder was not leaking, check your brake lines going to the rear wheels.

Start with brake in the rear that is the farthest away from the master cylinder ( if your master cylinder is on drivers side start with passenger rear,pump up brake pedal until hard have someone else open bleeder valve until air or fluid squirts out,while holding brake pressure even if goes to the floor dont release pedal until bleeder valve is tightened or you will **** air back into the line,do this several times making sure you get a full stream of brake fluid and no air,continue to other rear wheel and then proceed to front wheel furthest from master cylinderand then final wheel. if you still don't have brakes change master cylinder and bleed all brakes again.

adjust your rear shoes up so that the rear drums just turn, with them ajusted to a low setting the brake pedal will be low .
also when you start your engine it is noral for the pedal to drop because of the boster ! [ but not to the floor ]
