Eventhough this thread is very long, it does have some good info.

Brake flush every two years?! U'r kidding right?

You probably will want a motive brake bleeder
access to 4 jack stands and a jack
wrenches for the bleeder screws.

What does your master cylinder reservoir look like? If it has little black caps, get new ones before bleeding.
