Your brake booster is probably bad due to a loss of vacuum. Try this test: with the truck off pump the brakes about four times then while holding the brake pedal down, start the truck, if it drops slightly (about 1/4 inch)your booster is not the problem/ no drop booster is the problem. You will notice that this problem will get progressively worse and your truck will begin to rough idle when you stop. Get it fixed ASAP. Booster usually costs about 100 bucks and replacement is about a 2 hour job.
