forgot to mention, the truck seems to roll freely in neutral, so I don't
think one wheel has the cylinders stuck.
It seems more like a proportioning valve (if the truck has one) is putting
all the flow to one wheel.
The proportioning valve works from back to front not left to right. I
would check for sticky calipers because I have seen them stick in all
brands with age as the pads wear and the puck expands and contacts a
corroded area in bore. Sometimes you can get more life out of them by
installing new pads and forces pucks back into bores were there is no
corrosion and not let pads wear down to point it sticks. The only real
fix though is replacing them if they are sticking.
If it has rear drum brakes, he may have a leaky rear seal and oil on the
shoes. That's closer to what he's describing. Easy to check, just look at
the back side of the rear tires and wheels.

What year is this truck? if its a 2nd generation truck then it has drum
brakes in the rear. if only one wheel is sticking on the rear axle you may
want to check for oil contamination on the rear brakes. axle seals do go
bad over time and can leak rear axle lube into the brake drums.
