I have a 04 350 with stock wheels.Replaced rotors and pads a month ago.When I apply the brakes for a moment my truck pulls to the left and then seems to sstraighten out.I looked at my rotors and my left rotor is working alot harder than my right rotor.The right rotor looks like it still has some faint machine marks on it.I felt them and my right is still pretty smooth while my left is smooth but being used.Instead of my left sticking is it possible that my right just is not working properly and if yes how do I go about trouble shooting the right caliper for proper operation.

 

try bleeding the right caliper again

 

possibly the rf brake hose colapsed and restricting flow so it is slower to engage the caliper

 

Usually when a hose goes bad it wont let the fluid back to the master which makes the caliper hang up. If one side is turning harder than the other, try opening the bleeder, if it frees up then the hose is bad if it doesn't then the caliper is bad or its hanging up on the sliders. Make sure your pads and sliders are free and the sliders are well lubed. You may even have a bad rotor. If the surface of the rotors where not the same when you took them out of the box, then you will end up with a pull. they must have the same machined surface or it will pull.
