Well I have a problem with my truck that I am pretty sure is the brake rotor. What happens is when I am going down the street I let off the steering wheel and apply the brakes really easy where they aren't even barely doing nothing and my steering wheel will start to pull to the right, if I apply them harder or really hard the steering wheel will turn to the right really fast and I don't mean gradually or like a 90 degree angle turn, it will turn pretty fast where say if I wan't to enter the freeway and I have to make a right hand turn (I did this today about 2 hours ago) I will let off the steering wheel apply the brakes and it turns for me. Well my question is, is this because of warpage on the brake rotor? What other possibilities can it be because I can eliminate it being the front brakes because my wheel shakes already because some jackass didn't balance and align my wheels/tires when I got new tires put on so the front already shakes and I know that you can eliminate it being the front if it shakes. I can't tell it shaking anymore when I do that but all I know is that this isn't normal at all and no it's not the alignment because if I let go of the wheel and go down the street the wheel shakes a tad at about 40-45 MPH and it doesn't turn the wheel any, only with brakes on.
Sorry for this being so long but I am just telling you guy's what I am doing to eliminate problems.
Any help is greatly appreciated. Thanks.
