2wd vs. 4wd brakes

When changing a truck from 2wd to 4wd dose any thing need to be changed in the brake system for them to work right?

The only thing I have run into is the front brake block for 2 wheel drive has 2 connection's where the 4x has 1 so I had to plug off 1 side but it work's just fine . I do have a 4x4 block I am going to install when it goes in for Paint .

ok that's kind of what I thought but I wanted to sure, I was having a hard time getting good pedal but it turned out the ABS valve for the rear went bad.

If it was Me I would Bypass that vale they tend to go out for no reason . I didn't use 1 on my truck either .
