Default Flushing brake fluid question?

Its been a couple years, should the ignition be on or off?

The last time I removed what I could with a turkey baster, started on the right rear, then left rear, right front, left front, until had clear fluid at all wheels.

Any other words of wisdom would be appreciated.

Key can be off, I haven't found wheel order to be important.

Wheel order may be important given your year (presumed 96 based on ID) has an ASR/ABS unit which has valving which can be pushed out-of-position if bleeding in the wrong sequence.

Suggest following the wheel sequence in the FSM.

Also, don't forget to first bleed the ASR/ABS unit (compartment behind driver seat).

Key off.

Drain as much fluid from the reservoir as you can. Fill it with new fluid and start with the right rear wheel. I will slip a clear plastic hose onto the bleeder and put the hose into a glass jar. This way when I pump the brakes you can see the new clear fluid come out the hose into the jar. Don't let the fluid in the reservoir go empty. Have a friend constantly fill it as you pump the brakes.

Once you have clear fluid coming out the right rear, then close off the bleeder and go to the left rear. Repeat the above. Then move to the fight front and then the driver's front.

Since you have a 96, use DOT 4 fluid. There was a recent thread about break fluids....check it out.....

I have aways followed the order you identified without incident or problems. I couple of years ago I purchased a Motive brake bleeder which works like a charm. Check it out....

I used the same process a couple years ago. Pretty simple.
