I am having the front brakes done on my 2019 ES, and was wondering if I need to have the shims replaced as well? The reason for the brake replacement is that one rotor is badly rusted( The car sat for quite a while at the stealership as it was the previous model year. I did not buy the pads from Mitsubishi as I can't afford their price. Will the OEM shims work with aftermarket pads? The pads are Wagner Thermo Quiet Ceramic, which come with stainless hardware but not shims. Any advice would be greatly appreciated.
