So everything has been working great... until Saturday.

I used the truck to move my travel trailer and when I got home and unhooked the trailer I noticed the truck was quite hard to move and I could smell brakes.

Upon further investigation I find that all four brakes are dragging slightly. More brake pressure on the front tires than on the rear.

Could it be the proportioning valve?
Does anybody know where the prop valve is?
When I bled one front brake the other front wheel released its pressure as well.
ANy other ideas?
Thanks
