Seems the question of how to sort the discs (rotors over the pond) on a Pathfinder comes up quite regular, and no surprise either given the cost if you have them done by a garage. I managed to do these myself yesterday, first time, straight forward enough with basic tools. Did a little video of the project to as it may help others. Its a little long and I'm no producer / editor but it basically shows the process start to finish for the front axle. Hope its useful to others here and helps you keep your pathfinders on the road safe and your money in your pockets.
Sound is quiet at times , I was using a Kodak Playsport and has my back to it at times, motorway in the background accounts for the road noise.
