    Is the rotor warped? Bleed the line and try it again. You could have an air hole in the line and drawing in air to that side.

    Re: can\'t figure out problem

    the proportioning valve only controlls front to back braking. have you tried new pads? i had the same prob. and did everything i could think of to fix it except taking to a priest. then i replaced the pads and holy cramp it's fix, i also had the rotors turned and that helped a little more

    Re: can\'t figure out problem

    If you have replaced both calipers and pads Check the rotor to see if it is out of round. Also check for worn suspension and steering components. Tie rods, shocks, ball joints etc..

    Re: can\'t figure out problem

    I had the same problem, Although I screwed up and corrected 2 things at once so I don't know what fixed it.

    1st I had a cracked frame on the steering box, Weld on kit and brace.

    2nd I replaced the rotors, calipers and pads.

    My quess would be your rotor if you steering box is o.k.

    Re: can\'t figure out problem

    Do you have any lift on your truck?It could be bump steer caused by the front of your truck diving durring braking.

    Re: can\'t figure out problem

    I would suggest rotors are not right, meaning warped, grooved or something of the sort. You can warp rotors by not tightening your lugs correctly too. You need to do a cross tightening instead of going around the clock with them. Sounds silly, but true.

    Re: can\'t figure out problem

    Watch out for a faulty brake line too...I had a kink or a bubble or something in my right side brake line. Wouldn't let the brake fully release, so when I braked, I got a pull to the right because basically all the pressure went to the one right side brake. Just something to look for if the rotors don't turn out to solve the problem.

    Re: can\'t figure out problem

    If it's lifted then I would say it's lift related. Either its not got a steering correction on it or it's the sway bar binding when the nose comes down under braking.

    Re: can\'t figure out problem

    Sounds like a bad brake hoses to the calipers. Replace them both in pairs. They are cheap. Make sure you bleed the system good too. Also check for a worn ball joint, this will also cause the symptom you are having as well.

    Re: can\'t figure out problem

    I agree with replacing the hoses. my buddy's motorhome was having the same problem. we changed everything but the hoses and still had the problem. changed the hoses and the problem went away.

    start with the hoses. cheap and easy.

    Re: can\'t figure out problem

    I had this same thing happen to me a couple months ago. Looked at the pads and rotors, pads had nothing left and my rotors were glazed over. I would check them out.
