For both of you, an Automatic brake bleed is where a "capable" scanner takes over the bleeding process and shuttles the antilock valves while the occupant has his foot on the brake pedal. You will feel the pedal go down a little and stop. Then go down a little further and stop. And go nearly all the way down and then come back up. This is all done by the scanner.

A dealer obviously would be able to do this for you. A highly knowledgeable independent shop also. Since I have my own Solus, I do my own. I had bled my own brakes the normal way for years. Then I finally looked deeper into the 4 books of the shop manual and found the automatic bleed process and have never had a better pedal feel since.

So from page 5-249 in the 98 GM shop manual:

Do a standard 4 wheel bleed procedure
Press the brake pedal firmly and run the scan tool automated Bleed Procedure once.
Bleed all 4 wheels using the standard process again.

I don't understand the influence this process has on the brake pedal firmness and grab but it does. If you aren't doing it, you're leaving a lot of good on the table.

Good luck

First I've ever heard of this & I have 2 long-time buddies that have been employed @ dealerships most of their careers. I mentioned visiting the one @ the Ford dealership he works at (it's within walking distance from where we both live as well). When he wasn't @ Ford, he worked for higher end independent shops so he's familiar w/GM products.

I'll hit my buddy up that's the GM lifer & see what he knows (or can find out).

Thanks for the follow-up & explanation of the 'term'.
