Search on this forum, or try the following link. The link has a variety of comments by folks that have performed a DIY for brakes on what appear to be both fixed and floating calipers. If you go about two/thirds down the page on the attached link, the WIS instructions are also included for both fixed and floating calipers. Hope this helps.
