Hi Guys, have been really utilizing all the knowledge on this site to do maintenance for my recently acquired 2013 128i SULEV with 54K miles. Good news is Carly shows no major errors.

So far I've changed the oil, oil filter, air filter, cabin filter and plugs thanks to all the posts on the site.
Pending is coolant, trans and diff fluids but logistics are hard with no reliable access to garage - apartment living in NYC.

I started on a brake flush yesterday since the car is a few months overdue and decided to investigate a banging noise I've been getting from the rear.
To my surprise, my pass side ebrake brake shoes were floating free and the bolts and springs were bent and mangled, loose in the hollow of the rotor and backing plate was a scratched up, bent and the mounting points were flared.
Thankfully I had the rebuild kit and managed to rebend the metal on the backing plate to get the new bolts and springs to seat. Ebrake needs some adjustment but holds reasonably well.

Now to my request, while in the process of flushing the brakes, I managed to snap off the bleed nipple on the rear caliper(likely because I was turning in the opposite direction).
It sheared completely flush to the caliper housing so I just ordered a reman rear pass caliper that should be here in a few days.
I am looking for instructions on how to remove and reinstall the caliper to the brake line?
Does anyone have any experience or guidance on how to approach this?
Many thanks!
