Have lost having a good brake pedal after my rear disc conversion, no residual valve or proporting valve in use. Believe it's got to be my MC/booster combo. For those running after market 4 wheel discs what system or combo are you using.

Brakes front are SSBC conversion (Wagoneer/ 1/2 tonne pickup) 75mm piston
Brakes rear are Nissan/Suzuki conversion 38mm piston.

Using original 75 Jeep manual pedals so I think 6:1 ratio

Master cylinder/booster is what was on it when I got it, Mercedes 300d disc/disc. For those who followed my build will understand why the Merc stuff is in it.

Opinions/suggestions welcome

firstly are you sure you have all the air out

if so I had to change the length of the rod that is pushed by the pedal onto the master cylinder. Mine was too long causing brakes to be on, yours may need lengthening. Its worth a look

its a pain if its the rod that needs adjusting do it small increments like 1/4 or 1/2 turns as it will cause brake bind if its too long ..
