54 Cad; 4W Disc Conversion; SOFT PEDAL

[Dennis in CT]

So I am throwing this out there to you Caddy guys with the hope that one of you  can help.

 

I recently ordered and installed 4 discs on my 54 Cad which I purchased through Caddy Daddy. No issues installing, but I no matter what I do, manually bleed or power bleed, I CANNOT get a hard pedal - instead it is squishy. There are no fluid or air leaks, and I have bench tested the Master several times - it seems fine. When I have plug the front and rear ports, pedal is hard a rock. I have tried isolating the issue by blocking just the rear port, then bleeding the front calipers (and vice versa) and I still get a squishy pedal. So it would appear that all things point to the master, but why does it work on the bench? I am thinking that maybe the bore size is wrong? I have mounted the new MC in the same exact spot as the old one, which means it is just below or sorta even with the calipers, so perhaps I need to install 2 lb residual valves? But would that really make for such a squishy pedal?

 

Hoping some brake genius is out there that can help - many thanks

MAKE SURE ALL OF YOUR BLEADERS ON THE CALIPERS ARE ON TOP OR IT WILL NOT BLEED RIGHT.

YOU ALSO MAY NEED A EQUALIZER VALVE.

IF YOU ALREADY HAVE ONE CHECK THAT IT IS OPERATIONAL.
