My pedal on the master cyclinder travel halfway to the floor I installed two new front wheel cyclinders, bled brakes just not having good pedal , I was looking at auto zone the sell a booster mastercyclinder and othere here said something about adding a dual master cyclinder non booster from a 70's model. Looking for direction?

Thx

I added a non booster master from a '76 half ton . I needed to add the proportioning valve as well , but once the new lines were run , it brakes pretty good for a 4 wheel drum system .

Are the brakes adjusted properly? If they are not it will give you alot of brake pedal travel..
