How could you possibly replace the calipers and not get air in the system?

Go bleed your brakes. It needs to be done occasionally anyway. I'm doing mine today on a "project" Fiero as well.

[EDIT] Remember to use the proper sequence (which is Fiero specific) - LR RR RF LF

Yep. I just did mine. I used the hand vacuum pump to start, then went back around all fours the old fashioned way because I dont trust the pumps. They are good enough to get things started but because I can still see bubbles, they aren't done. Once I dont see any bubbles, then and only then will I say the brakes have been bled.

Why? I was always taught that you start farthest away and work your way in. The instructions to the pump says the opposite! It says to start closest and work your way out.

After replacing the calipers? You need to find a new technical advisor ASAP.

Yes, your brakes need to be bled all around. Take your time; do it right.

I was also taught to start with the furthest caliper from the master when bleeding and to work your way closer (as you were taught). So, what are you going to follow... how you were taught or what the directions from some cheap pump tells you?

Marvin, more words of wisdom please!

Go ahead ... splurge and buy a whole quart of DOT3/4 brake fluid. That is more than enough to bleed and flush an entire system. Don't be tempted to use some old fluid that has been sitting on the shelf, opened, for several years. Brake fluid is hygroscopic; it readily absorbs moisture from the air.
