I presume you are asking about removing fluid from the old reservoir because you want to clean it out prior to installing the old reservoir on a rebuilt master cylinder, or because you want to get rid of the dirty fluid and replace it with new prior to bleeding the brakes. Just make sure the reservoir is full of fluid before you touch the brake pedal.

You can go to Wal-Mart and buy a plastic turkey baster for a dollar or two, and use that to suck out the old fluid in the reservoir. I store mine in a zip-lock bag to keep it clean. Don't use it for anything other than brake fluid or buy a new one the next time. You don't want to introduce any liquid other than brake fluid into the brake system.

There are some procedures that for safety reasons should be done with a proper service manual ONLY. Factory manual, Chilton'*, Haynes, or Clymer. The liability involved if this were put in Techinfo, and something went wrong are too great. This is also why I left some torque spec info out of Techinfo.

I asked an autozone guy how to bleed,

He said for the brake system with ABS, the ABS should be discharged by pumping the peddal more than 60 times.

Do I need to do that?.

By the way, what about the inition?. the guy told me that I don't need to ignite the engine, and shifting to 'on'switch is ok when I bleed..

Thanks.. as always..

According to the factory service manual for the '92 Bonneville with ABS, the bleeding procedure is pretty much as I described it EXCEPT they instruct that before you start to bleed the brakes, you deplete the vacuum in the booster by applying the brakes a few times with the engine off. (This is the power brake booster vacuum can behind the master cylinder, NOT the ABS pump.) They also instruct that the helper press slowly down on the pedal and hold only once for each time the bleeder valve is opened. Then the pedal is released and you wait 15 seconds before pressing down only once again. This is done with the ignition and engine off.

Maybe someone on the site with a '93 FSM can check if the procedure is the same for your car as it is for mine.

I would not touch the ABS system other than to very carefully clean, remove, and plug the top end of the hose that runs down to the ABS pump reservoir when you change out the master cylinder. It is very important that you do not introduce any dirt into any part of your brake system.

Don't ask ANYONE at Autozone anything about cars.

Ignition on or off has nothing to do with it. Nor does pumping the brakes 60 times. Get a service manual, and follow the procedure to the letter.

Edit:

Asking someone that works at Autozone a question about your car is like asking the guy at McDonalds what kind of marinade he uses on his steaks.
