Please can you help i have had my shogun warrior auto 3.2di for 9 months and have done 6000m in this time it has needed to go back to dealer 3 times due to wobble whilst bracking each time they have skimed the disc is this normal

please help

skimming discs is a viable solution but generally you can only do this once or twice as you remove too much material to make it usable past that.if there is a judder issue due to warping discs then skimming will not cure long term.they warp due to overheating and making them thinner makes them heat quicker.if they have truly skimmed 3 times I would request new discs as they have to be very near if not below legal minimum.if it is under warranty they can do it FOC providing they do the correct paperwork such as runout measurements and discs thickness measurements(8 segment measuring.)pm me if you need more info to assist you
