Brake shimmy

I have an issue my dealer can't get fixed.
Sometimes when I apply the brakes I shimmy. The dealer has turned the rotors, replaced th erotors and the issue comes back.
Any ideas? It's going back on Monday for more repairs on this issue, just wondering if any has had the same issue

 

If you get shimmy when you apply the brakes, then your problem is probably the rotors. I would take the truck somewhere other than the dealer. This problem is not uncommon-I have developed a slight shimmy myself. I will remove the rotors, and a local machine shop will turn them for $10.00 apiece. Unless something weird is happening, this seems pretty straightforward.

 

Having rotors machined does not last. Maybe a few days. If you have a brake pulsation the rotors must be replaced. Try to avoid heating the brakes a lot.
