I dont have any problems an i have been slidin mine the past 3 winters an havent had to change out the shoes and i used my parking break every time i park too. Right now i only even have one side though cause i backed the other side all the way off so it doesn't engage due to the cable sticking. I suppose that could be related but unlikely as that started happening in the middle of the summer. im currently waiting for my new cable to come from gtx.
