How do you replace the master cylinder on an ABS 6 car?

Wow that’s an old thread that has never been answered.

 

I ended up using a used ABS/Master Cylinder assembly from the scrap yard.

 

So you replaced your ABS/Master Cylinder and you didn't disassemble the original one you no longer needed? If so, that's a VI-O-LA-TION!!! I consider it my constitutional duty to disassemble every nonfunctional part I remove from a vehicle with the only rule being: Do Not Void the Core Credit. Maybe I suffer from an overabundance of free time, but I consider disassembling stuff to discover how it works a basic instinct like eating or f*cking or like the explorers who sailed into the Atlantic to see what lay over the horizon. I mean, you know someone else on a forum (#ME) could benefit from the knowledge acquired by disassembling a part in question especially when a manual says "Thou shall not replace, inspect or actuate without said overpriced proprietary tool."

 

So are we mice or are we men? Who among us has attempted the fabled Delco/Delphi ABS-VI master cylinder swap without the loathsome Tech 1 scan tool?

I can do it with no problem at all without a Tech-1 on my Olds Achieva!

 

I have a newer Tech-II. :lol:

FWIW, a long long time ago, there was a scan tool that read the weird Delco-IV OBD-I pinouts/standards (like on an Olds Achieva) and it was also able to issue a re-home command. :) My old ABS scanner died many years ago. I haven't seen on one ebay since. But, I also don't search for ancient ABS scanners. :)

So the purpose of the Tech-1 or Tech-2 is to re-home the abs module?

The purpose of the scan tool is to re-home the motor so that the brakes can be bled properly.

 

For bleeding w/o a scan tool see one of the following links: http://www.aa1car.com/library/abs_bleeding.htm or http://www.saturnfans.com/forums/showthread.php?t=146855

 

 

@ Joe - The old scan tool that you're thinking of is probably the OTC ABS Reader. It will read the Delco IV and a lot of other older systems. I picked one up cheap a few years ago on ebay just to have. I can grab the part number off it later if anyone else is interested in trying to track one down. You're going to have to look on ebay or craigslist randomly to find one. They don't show up very often anymore.
