John Deere 2750 Brake problem

[Butters]

My left brake pedal was going down to the floor with no action. Per the dealer's suggestion, I rebuilt the valve body that connects to the pedals.
Now, the left works, and the right goes to the floor. Even stranger is that when you push both pedals at the same time, they both go to the floor and no brakes. Any help would be appreciated or I will have to have them come out and fix it for probably a lot of money.

I got it. Apparently, very little wear can make the brakes fail. replaced two valve assembly parts and it is like new.
