I'm not finding a huge amount of information online about doing a caliper (only) replacement. My rear Shimano MT500 is having issues and I urgently need to get it working, therefore I've purchased a brand new caliper of the same model.
I can't seem to find information on best practices on how to do it though.
Should this be as straight forward as draining (?) the oil from the brake system, unscrew the rear caliper from the hose, attach new caliper to the hose and run Shimano oil through the system/bleed?
Are there any gotchas to look out for? Can I expect the unscrewing the hose/attaching the hose to be a simple process?
