Rear Brake Revisited #2 Thanks again @HuffnPuff for the suggestion on changing the calipers. This is what I ended up with. Couldn't find SLX brakes with a right lever without waiting for over a month on delivery. Decided on Deore XL calipers and Base Deore levers. As far as I can tell all I gave up was "adjustment on the fly" at a cost just over half of the XL levers. Here's how the routing worked out. Mounting with an adapter looks pretty straightforward. However... the size and shape of the XL caliper is just different enough from the first caliper that mounting at the top of the disc is now possible. If I modify the seat support brackets, rotate the caliper a little from pictured, and create post mounts the hose routing cleans up even more. Just need to decide which way to go. To me either looks better than the previous routings.
