I've had several emails from guys who want to purchase rebuilt calipers for their seven. A friend of mine owns a parts warehouse just north of Cincinnati and sells them for $45.00 plus core. These are quality rebuilts, I've used them. If your interested: Imported Parts Warehouse, Fairfield, Ohio (513) 874-9881 ask for Mac, Tell him Bob told you to call. He can also get you other parts for your bimmer at good prices.
