Loukanous

Howdy y'all, I've recently acquired a 2017 Chevy Silverado and have minimal maintenance experience. I have a broken parking brake pedal assembly that I will be replacing myself, and due to very little coverage out there on the internet, I was hoping there were some folks out here who experienced the same problem or have guides on the issue. I mostly need to know what to disconnect beforehand, and the spots where the assembly is bolted onto. I'd appreciate the help.
