pulling to the right!

[Perry C]

When ever I step on the brakes hard and sudden the truck darts to the right, if I press slowly it doesn"t seem to pull. I felt of the wheels after driving and there not hot like a caliper sticking. But I guess it could be any other ideas what it might be.
Thanks in advance.

One of the brakes on the left is not grabbing as hard as the one on the right.

Not sure if you have found or fixed the problem yet, but figure that I would give some help regardless. Worn out brake hoses can cause pulling under hard braking. Over time the rubber in the hose breaks down (why alot of the time you see brake fluid in the master cylinder that looks black) and can begin to collapse/swell. When it gets to that point it allows unequal braking pressures side to side resulting in the vehicle pulling to the side with the better brake pressure.

It's amazing how much crap can be inside of a brake system...I just bled my brakes after replacing the hoses up front, and I had all sorts of little floaties and crap in the old fluid. I bled it until I had nice clean fluid coming out.

your left front brake hose is ballooning inner layer is broken..

When you're done chasing brake hoses, and caliper function, take a look at the bushings at the fronts of the main leaf springs. When these go bad, the truck "falls" toward the bad side. Replacement bushings are available. There are rear bushings, and these should be inspected as well.
