That's the way they are going to work when bobtailing, every truck we have is like that. Most of them actually have a decal on the dash or somewhere that says something like 'increased brake pedal effort may be requires when bobtailing' or something to that effect.
It started acting like this about 8 months ago, I understand what your saying but this is really bad. I mean you have to go 3/4 pedal to get braking action, then a t .76 pedal travel the wheels lock up. When pulling a trailer at normal braking you can feel the trailer doing all the braking.
