its my fault. NO BRAKES Options

[CrossCudi]

So my spacers came in with my extended studs for my rear,
I raised my car, removed the wheel, found my 2 screws to insert in
the available location to removed the rotor. as I kept screwing away
the rotor was moving out but it was coming off. than I noticed I had my Ebrakes up !!!!

I knew from the amount of screwing I did I had to damage something inside.
I released my ebreaks and the pressure was releases and rotor came off along with these:



I was so mad at myself, so I continued with the process,
the other side was done successfully and noticed that
those parts came from here:



I knew that was a crucial damage...

got in my car after I was done and break pad when pressed just sunk straight down with no pressure..
stepped on it a few times and still the same..

now I have no brakes and looks like I will need a new driver side rear drum setup.. ?
