Well i have a weird thing going on with the anti lock brakes. Its normally more noticable when its cold. coming to a slow stop you can feel the anti lock brakes pulsing slightly or more noticably if you hit a bump braking at slow speed. the only mods to the truck are 285/70/17 inch tires and a leveling kit. Not sure whats going on with it, but i thought i should check here before getting my wallet lightened by the dealership.

 

I would check the calipers and pads as it sounds as if one of the wheels has a brake that is tighter that the other three.

 

Well its due for front brakes anyways the rotors are warped a little and i have to chang ethe right axle shaft might kill two birds with one stone
