I buy Bendix loaded calipers. They're rebuilt calipers (by Bendix) lubed, with new rubber parts, and Bendix TitaniuMetallic pads installed. They are $75 each and are quick and clean. Just R&R the calipers, bleed and go. I've never had one go bad or be defective out of about 12-15 pairs. Sorry about not using the "best" performance product but my limits these days are a little "spirited" driving on a country road every now and then. The rest of the time I'm cruising the boulevard.
