Handbrake question and spacer question Options

[Random_Stranger]

Ok, I changed out my rotors and on one side in the rear, (i have discs all around) I have noticed when I put my hand brake up, I heard something that sounded like a spring popping something off. Since then, I literally have to pull my handbrake all the way up just to keep my car in place. So my question is, for anyone who has changed out rotors before... Where the heck do I assemble those two springs? I am going to describe it as best as I can.

On the last rear rotor I did, I noticed a spot for the little retainer part to sit upon, and then you have the pin that goes from behind that hub that faces you, and it appears the spring goes on the outside (the part facing you) over the pin, and there is a button that you position to hold the spring in place that is secured by turned to lock onto the pin. The first one that I did (which I am guessing is my problem), I sort of just placed those behind the hub, yet assembled. So I was just wondering if all were to be assembled outside the hub or behind it near where the pins come out? Since this is my only car and daily driver at the moment, I have not time to let it sit and examine all this, which is why I am asking. It is really bothering me because when I drive, sometimes it seems I hear something rubbing making a scraping sound on that side.

Another thing I have noticed, was that since my offset is +48 on my wheels and having gone from 215/40/17 to 225/45/17s, would spacers be a good option (meaning trustworthy, because honestly the thought of using spacers kind of scares me or any type of "Adapters" for that matter on anything) for me at this point, avoiding getting new rims with a better offset for the moment? I noticed when I make a real sharp turn, I can hear them rub. I look under and can see some tire markings on my rear struts, although there is good clearance for just driving straight (Maybe it has to do with the springs and needing tighter suspension like coilovers maybe?).

Anyways, if you read this far, I thank you and if you have experience on this to shed some light, I am really eager to hear how I can correct my issue.
