I didn't. I used a Motive pressure Bleeder works great. It's costly ( $70.00 ) but I have 4 cars so it pays for itself. Very easy to bleed the whole system by yourself.

Default Gravity bleed

I just refilled the system and cracked open all the bleeders..Then, as long as you don't let the master run dry, most of the bleeding takes care of itself.

Daffy,
Sounds good to me,
Thanks
You think I should run some brake fluid thru there to clean any junk out of the lines since it's been sitting for a couple weeks with no calipers on it.?

I replaced all 4 calipers and some of the brake lines. I got a mightyvac at NAPA for $25. The mvac is nice for troublshooting the headlights as well.

You can pour as much fluid thru it as you want.. I just put something to catch the fluid to keep from making too much of a mess..The fluid should look nice and clear when all the old crap is out of there..

Yes, flush those lines thoroughly, brake fluid will absorb water out of the air, so you probably have a teeny-weeny bit of moisture in those lines if the have been exposed to the atmosphere for several weeks. Also, this may seem obvious, but you seem new to this, so I'll just throw it out there: be careful what you get brake fluid on, it will peel paint pretty bad.

Scott,
That advice is to late, I set a rag down on the fender that had brake fluid on it and it wrinkled the paint pretty good before i even realized. But thanks anyhow for the warning.

I will flush it good before I put the new calipers on.
