I am converting a 65 C-Body from the single reservoir master Cylinder and Drum brakes to a Dual Master and Front Disc Brakes. The brakes are still manual brakes and everything is done, but I am having trouble getting the pedal to come up and I am not confident I am getting enough fluid distribution. I used the original brake push rod from the single master cylinder with the dual, the pedal travel seems right, does anyone know if there is any difference in length? I am using a new disc/drum master cylinder, but the brakes just dont feel quite right, the pedal will travel to the floor and return to near normal, but it seems like I have a little slop at the top position. Any Ideas?
