Not sure I have the where with-all to tackle this one. But for the sake of argument, whole job, how long would this take assuming the person knows how to do it? They are disc brakes in the back, btw.
If you are looking for an idea of labor costs just replacing the brake line from front to back should take a few hours at the most depending on how hard it is to get the line tucked into where the current one is sitting. Once the new brake line is installed the air has to be bleed out to get a solid brake pedal.
The job I did on my Blazer took about 3 hours total.
The bleeder screws need to open to be able to do this and depending on the age of the car and the type of weather it has been in can determine if the bleeder screws open easily or if they get rusted in and wont open.
In your case having rear disc brakes the bleeder screws on the rear disc calipers are generally easier to open than a rusted up bleeder screws on wheel cylinders on drum brakes because the bleeder screws on the rear brake calipers are bigger and can take more torque to open them before they brake off.
If the bleeder screws on the Calipers dont open easily it helps to wrap the caliper next to the bleeder screws and even tap the bleeder screws as it can loosen the screws up with the vibration.
If the bleeder screws still dont open the next option is to apply some heat. At home a propane torch is about the only option and can work. With heat and tapping the screws and caliper my guess is you could get the bleeder screws open so you can bleed out the air to get a solid pedal.
If the bleeder screws are stuck so tight that they break off then the only way to bleed out the air in the new brake line is to get new rear brake calipers which will run a good amount of money.
I mentioned I bought a roll of brake line and put in one new piece from front to back. The thing is when doing it this way you need to flare the ends so the brake line seals correctly and does not leak the brake fluid.
To do the flaring at the ends of the brake line you need a special tool but where I am I used Advanced Auto to buy my parts and they have the tools you can use. You pay for the tool and get your money back when you return it.
Another way to do it without needing that tool or having to flare the brake line is you can by pieces of brake line like 4ft long and then get connectors to put them all together. You get under the car and measure the distance of brake line you need and then go to parts store and get enough pieces to meet the length you need.
