For those that have successfully converted to Samurai disks, what size master cylinder bore are you using? I have been disappointed with the braking performance of this setup, and I think it may be the result of a MC bore that is too large. I am using a 1" dual MC mounted under the floor with a 2lb residual valve. The pedal is very hard. I am using organic pads and I did follow the break in procedure. Braking ability with front disks and rear 10" drums is definitely less than I had with 11" front and 10" rear drums. To complicate the matter further, I took the Jeep off road for the first time since I installed the conversion. Since then, the brakes have been almost totally non-functional. I can barely stop with the pedal pressed as hard as I can. If I feel the hubs after driving, they are cool. Normally they heat up significantly from the brakes. The pedal is still very hard. Any thoughts?
