Need help with brakes

[brock9334z]

My parents have 95 Cutlass Supreme drop top with the 3.4 V6. They drove it today and the brakes went to the floor.

Car has an honest 35,000 miles on it. It seems it needs a master cylinder. Car has ABS can anyone advise me how to bleed the system? I understand doing the bench bleed of the new master, my concern is bleeding the rest of the system.

Any assist you are able to offer will be greatly thanked. I will be driving 700 miles to do this so they do not attempt to drive the car to a garage while using the parking brake. 

Thanks in advance for any advice

Are you absolutely positive that there is not a rusted out/broken, brake line, hose or caliper? I know it has low miles but what you describe sounds way more like a break in the system then a failed master

Treat it like any other master cylinder, bench bleed it, install it it has a couple extra bleeders on the master, start there and then work from the back to front. a Vacuum bleeder would make it easier.
