ok so i got the check brake linings warning. dealer wants 1100 total for front rear, i have someone who can use OE bmw parts and do the job for 785. what is a reasonable price for front/rear, what parts are necessary for this and do i NEED to change rotors or is it just SUGGESTED? i know there are a ton of threads on this but by the time you get the info you need you've read a billion and a half of misc info thanks guys love you
