I want to thank all that replied. the problem turned out to be a bad right rear wheel cylinder. the rear right shoe was hanging up throwing the whole system kittywampus. I was thinking to hard and wasnt using common sense. I should of tried to stop the truck with the emergency brake first to eliminate the back brakes. Instead I went wild on the fronts. The rigth front caliper was sticking as proven by jacking up the front and spinning the tires eailer and need to be replaced. led to a very slight warped rotor. Chewing the autocrap boy about thier rebuilt calipers leading to a warped rotor was theraputic and a stress reduction. Otherwise pulled the rt rear hub and replace cylinder and everthing stops without pulling or shaking. The brake system should be ready for another 100k except the left rear caliper.
