Sounds like dealer rotors & ceramic pads?Nope!
But our Rig is due for new brake rotors and pads this time around.
(I'm replacing them mid to end October. Pads still have plenty of meat on them
but one rotor is starting to warp again, so I'll replace the whole lot.)
Is the warped one on the front?
I have 4 rotors on KJ. On the sedan I have never warped a rotor cause I use Hawk brake pads, which are available for the front on the KJ.
I would consider using Napa's Premium slotted up front and Hawk pads and definitely inspect the bearings for noise and movement.
I use severe duty Carbon Ferrite on sedan, very little brake dust and grab city.
