I had air tool, and the help of my knowledgeable father.

It wasn't too difficult. Everything is straight forward. The hardest thing was chaning over the proportioning valve, that was a big pain in the ass. Pick up/borrow/rent some brake line wrenches, unless you want to f-up your lines. they are special, better gripping.

bleeding brakes isn't difficuly, just time consuming. If you get one of the manual gismo's for bleeding brakes, be sure not to try and go too fast, or it won't work right. its better to have a friend pumping the brakes.

get 2x the amount of brake fluid you would normally buy. becasue you'll be bleeding the whole system basically, becasue it will be open to air big time, unless you don't change the proportioning valve and booster/master cylender.

overall, should take you a nice saturday to complete fully.
