No idea what mounting bracket you're referring to. GM typically doesn't use a bracket in the middle of their hoses. Sounds like a job best left to the professionals. If you had the new hose in your hand you would see any brackets are included already attached to it. If you don't know that, (no sarcasm intended), there are going to be other things you also don't know that can lead to problems. Insurance investigators and lawyers love to find signs of do-it-yourself repairs. I can't fault anyone for trying to fix their own car, but not when the potential for causing more problems is likely.
If the soft metal line nut is rusted to the steel line, that line is going to twist off when you try to unscrew it. Now you have another part to replace that must be carefully bent so it's oriented exactly like the old one. That often results in kinking it and blocking proper fluid flow to and from the caliper. A lawyer would have a field day with that even if the other guy ran the red light and caused the crash. And they WILL find those things.
Chances are the bleeder screw on the caliper is going to be rusted tight. If you snap it off, you must replace the entire caliper. To maintain even braking, you must replace both calipers at the same time. Do you know what to clean and where to apply the special high-temperature brake grease? Professionals know at least two tricks to get bleeder screws open. They also know a lot of things they can do to prevent noises.
How do you plan on getting the air out of the system once the new hose is in place? One simple, common pedal-bleeding mistake can destroy the master cylinder. Now you need more parts. Another built-in problem affects only GM front-wheel-drive cars. That causes no brake fluid to flow to one front wheel. Other than the fact that no fluid comes out when you try to bleed the air out, you will never know this happened until the brake pads wear out real soon on one side and they look like new on the other side. Think lawyers don't know about this and how to check for it?
If you still want to tackle this job, have the new hose in hand and holler back. I'll type a long list of things to watch out for. In particular, do not get any type of petroleum product such as engine oil or power steering fluid anywhere near brake fluid. Even a little oil residue on your fingers that gets into brake fluid will result in a REAL expensive repair. That expense can exceed the value of the car if it has anti-lock brakes.
