Over the last month my brakes have started to squeak at low speeds right before I stop or as I'm creeping in traffic. It's gotten a little worse everyday so I took to dealer and of course they stopped. Day later started again at every stop. I heard the slide pins aren't lubricated the best from the factory and the truck only has 14k on it. Any thoughts or suggestions from anyone else that's had this problem

 

Mine started at 20000kms. Lots of noise coming from them, same situation as you describe. Dealership machined front rotors. No noise for 2 days then started making noise again. Had it out with dealership and they are putting new rotors on it now and going from there. Lots of people have warped rotors and I was pissed at having machined rotors with 20000kms and 1 year old.
Looking into upgrading brakes. I put Powerstop on my last truck and wife's edge and they are pretty good.
