2015 Shimano Rear Deore M785 XT hydraulic Rear brake

This brake was purchased new but had a warranty issue in the caliper after 3 months of use that was discovered. Shimano replaced the caliper with a new one. The lever is original. There have been no crashes with this and condition is 10 out of 10 on lever and caliper. The line was cut to fit my tallboy and is 4.5 ft long and is un bled. Shimano sent bleed block and new fined brake pads. I am selling this because while it was being warrantied over a 2 month period i ordered a new shimano brake set so i could keep riding. Please let me know if you have any questions.
The nomenclature on the brake caliper is BR M785 and the lever nomenclature is BL-M785-B.
