So I've had my 525i for about 6 months. About a week ago I had the caliper bolts fail on the right rear brake, and smashed it's self into the rotor shield. Cut the brake line and broke the caliper arm. So I've tried to get the OEM caliper replaced, but it's not available, so the best option I could come up with is to upgrade the rear brakes to the 540i brakes which are available.
Does anyone have any advise or something I might not be thinking of when doing this swap.
